Answer:
Simplifying
3x + -10 = 2x + 30
Reorder the terms:
-10 + 3x = 2x + 30
Reorder the terms:
-10 + 3x = 30 + 2x
Solving
-10 + 3x = 30 + 2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2x' to each side of the equation.
-10 + 3x + -2x = 30 + 2x + -2x
Combine like terms: 3x + -2x = 1x
-10 + 1x = 30 + 2x + -2x
Combine like terms: 2x + -2x = 0
-10 + 1x = 30 + 0
-10 + 1x = 30
Add '10' to each side of the equation.
-10 + 10 + 1x = 30 + 10
Combine like terms: -10 + 10 = 0
0 + 1x = 30 + 10
1x = 30 + 10
Combine like terms: 30 + 10 = 40
1x = 40
Divide each side by '1'.
x = 40
Simplifying
x = 40
