4x+3y=6 how do you solve for y Hello, I am not lecturing you but I would rather you understand how to do the manipulations involved in isolating a variable. You want to isolate y, Ok Start stripping ...

...3y = 2x - 1Now for the second equation:2y + 8x = 102y = -8x + 10y = -4x + 5Since both equations equal y, they also equal each other, therefore:2x - 1 = -4x + 5Now just solve for x:2x + 4x = ...

What is x-3y=-12, 4x+6y=-12 in elimination ? then x = 3y-12, then 4(3y-12) +6y=-12, then (12y-48)+6y=-12, then 12y-48+6y=-12, then 18y=36, then y=2. x=3y-12, x=3(2)-12, x=6-12, x=-6.

4x-y-2z=-7 -4x+8y+5z=46 8x-3y+z=13 Type solve(exp1 and exp2 and exp3, {x,y,z})See cap images

argument error ti nspire 4x-6y-3z+-10 6x-3y-4z=-2 -4x+y=-6 What are you trying to do? Could it be that you entered a + sign followed by a - (minus) sign instead of a change sign (-). +-10

...any good in this particular case. Anyway, there is nothing you can do with such an expression (IT IS NOT an equation, just an expression) , except some cosmetic change 2x(2x-3y) or expand it

...exponent into the calculator? i.e. 4 to the negative second power. 4 ^ (-) 2 The ^ key is just above the divide key, the (-) key is just to the right of the decimal point key. -4(2x-3y) 4x-2(x

4x-3y=-6 Equation should be in slope intercept form. y=mx+b y=(4/3)x + 2 If this is homework, be sure to show your work.

...calculations, any electronics store has any number of choices. If you are looking for something to help with higher math (calculus) TI's TI-83 and 84are pretty much the standard. 2x+3y=2 ...

4x+3y=6 x=3 and y=-2
