Solve by multiplication and addition. Show each step of your work. x – 4y = -10

3x + 2y = 12

No one explained their answer when I asked before I'll give brainliest if you tell me how to give you brainliest because I dunno how :)

X - 4y = -10

I’m assuming we have to solve for x, right? So we have to get the “x” alone, so we do the opposite of subtracting and instead add +4y to -4y, which cancels out. Then, we add 4y to the other side of the equation, to -10. This then becomes:

x = 4y - 10

For the second one:
Once again, I’m assuming we have to solve for x. First, we have to do the opposite from addition because we’re added “2y”, so we have to subtract 2y from both sides of the equation. Now it looks like this:

3x = 12 - 2y

Still, we have to divide both sides by 3, because “x” is still not singled out.

So then, it becomes:

3x/3 = -2y+12/3
(The slash is supposed to represent division)

Once we’ve divided both sides, your answer should be:

x = -2y/3 + 4

X= -8

only if you are supposed to add the equations at the end
