Once again lets break this down by putting it into an equation. The supplement will be x. We know that 180 - x ( the supplement) will be equal to the angle but the angle is 2/3 the supplement.

Your equation should look like this x = 2/3 (180 - x).

Then we're going to multiply both sides by 3 to get 3x = 2 (180 - x)

You should distribute the 2 on the right side to then get 3x = 360 - 2x

You want to get x by itself but you can't make it just disappear because you need to keep your equation balanced. You're going to need to add 2x to both sides making your equation 5x = 360.

then you're going to divide 360 by 5 to get x = 72

subtract 72 (your angle) from 180 to get 108 which is your supplement.

If it's a bit confusing feel free to msg me and I'll do my best to explain it a bit better ^^;

5x + 3 = 7x – 1. Find x

nasty-shy [4]

Answer:

x = 2

Step-by-step explanation:

5x + 3 = 7x - 1

Subtract 3 to both sides

5x = 7x - 4

Subtract 7x to both sides

-2x = -4

Divide by -2 to both sides.

x = 2

Hope this helps and pls do mark me brainliest if you can:)
