Using brackets in an equation - Canon Office Equipment & Supplies

You could mean

(x / 2) - 20 = 150 then x = 340

or

x / (2 - 20) = 150 then x = - 2700

Wherever this type of ambiguity arises in an equation you should use brackets to resolve it. Note that in the absence of brackets a calculator will always choose to perform multiplications and divisions first.

2+5 = 7 -7 =0 x 6 = 0

this is a simple algebraic equation in which we have to calculate the value of 'x' using simple operations

7+(9-5x)=5(2-x)


step 1(pen the brackets) 7+9-5x=10-5x
step 2(add 7 and 9) 16-5x=10-5x

now as 5x gets cancelled both the sides of the equal sign therefore no solution of this algebraic equation exist.

You only presenting one side of the equation with what you got to get: (x-1)(x-4) = x^2-x-4x+4 you get that by multiplying the factors in the brackets with each other to expand the equation without the other side of the equation you can't solve for x

It does not matter what sequence you write in. The sequence followed by all is BODMAS. Brackets, Of, Division, Multiplication, Addition and Subtraction.
What matters is that you should separate the * and / from + and - with the help of brackets.

For negative numbers (not just exponents), use the +()- key to the right of the decimal point. For brackets, use the parenthesis keys above the 8 and 9 keys. You can nest more than one set if needed.

This is easy. First these brackets ( ) have a three numbers followed by an x y and z, the brackets mean we should multiply the like amounts: but first lets group like amounts by adding them up 3x+16x+6x= 25x then 8y+9y+11y=28y, now z...13z+14z=27z now the otherside of the equation which is always after the equal sign is 326+453=779, so now it is more simplified by combining like amounts:so now we have 25x+28y++27z=779 so now we must balance both sides of thr equation, what we do to the left side of the equal sign, we must also do to the right side of the = sign, so we need to get x by itself, so we minus 25 and are left with just an x, then if we take 25 off of the other side of the = sign, we must take 779-25 so now x is on the left side by itself then the the right side is 754, so now the x is solved X=754, then you do the same for y and z.

Just use parentheses for all brackets

While you may have removed the door with the hinges from the cabinet the nuts may have fallen down on the unit.
You may want to open the back panel or the bottom panel and try searching for the same, in case you need assistance mounting the bracket back on the cabinet once you have the nuts do let me know.
