Answer 6

Simplifying
2x + -10 = 10 + -3x

Reorder the terms:
-10 + 2x = 10 + -3x

Solving
-10 + 2x = 10 + -3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3x' to each side of the equation.
-10 + 2x + 3x = 10 + -3x + 3x

Combine like terms: 2x + 3x = 5x
-10 + 5x = 10 + -3x + 3x

Combine like terms: -3x + 3x = 0
-10 + 5x = 10 + 0
-10 + 5x = 10

Add '10' to each side of the equation.
-10 + 10 + 5x = 10 + 10

Combine like terms: -10 + 10 = 0
0 + 5x = 10 + 10
5x = 10 + 10

Combine like terms: 10 + 10 = 20
5x = 20

Divide each side by '5'.
x = 4

Simplifying
x = 4

:D party! Thxxxx so much

Answer 9

Wel!

Answer 10

Distribut the 5 to the x and -2 and distribut the 2 to the 10 and x. You get 5x-10=20+2x…..subtract 5x from both sides to get -10=20-3x Subtract 20 from both sides to get -30=-3x……-30/-3=10......x=10
