SOURCE: what is the answer to 10x minus 3x equals 20 plus

__joshua__,

X = 3 (**answer**)

__Here are the solution steps:__

10x minus 3x equals 20 plus 1

10X minus 3X is 7X (right?)

20 plus 1 is 21 (right?)

therefore:

7X = 21

now divide both sides of the equals sign by 7

7X divided by 7 equals 21 divided by 7

7X / 7 = 21/7

X = 3 (**answer**)

Are you entering any number before pressing the minus, add, multiply, or divide key? Those operations require two numbers; if you don't supply the first one then the calculator will supply the previous answer, which was zero.

For example, to add 2 and 3, press 2 + 3 = and you'll see 5. Now to add 4 to that, press + and the calculator will automatically supply the 5. Press 4 = and you'll see 9.

Do you need help doing your homework?

If so, here's a first attempt. It may be correct, and it may not be.

It's up to you to understand the process, and to make any needed corrections.

X minus 11 equals Y.

So, X is larger than Y.

So, 3 times X minus 33 equals 3 times Y.

Thus 3 times X equals 3 times Y plus 33.

Also, 3 times X minus 4 equals 4 times Y.

So, (3 times Y plus 33) minus 4 equals 4 times Y.

Thus 0 times Y plus 29 equals 1 times Y.

So, Y equals -27.
