3 (x -1) = 5x +3 -2x
Vika [28.1K]

Steps to solve:

3(x - 1) = 5x + 3 - 2x

~Distribute left side

3x - 3 = 5x + 3 - 2x

~Combine like terms

3x - 3 = 3x - 3

~Subtract 3x to both sides

-3 = -3

~Add 3 to both sides

0 = 0

All real numbers are solutions.

Best of Luck!

You can see a picture of this case in the figure attached: as you can see the cross section (in pink) is a triangle.

The number 49 has two square roots: 7 and _____​

Hope this helps!
