Answer:
x = 40
Explanation:
Equation:
Solution for x+30+(3x-10)=180 equation:
Simplifying
x + 30 + (3x + -10) = 180
Reorder the terms:
x + 30 + (-10 + 3x) = 180
Remove parenthesis around (-10 + 3x)
x + 30 + -10 + 3x = 180
Reorder the terms:
30 + -10 + x + 3x = 180
Combine like terms: 30 + -10 = 20
20 + x + 3x = 180
Combine like terms: x + 3x = 4x
20 + 4x = 180
Solving
20 + 4x = 180
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-20' to each side of the equation.
20 + -20 + 4x = 180 + -20
Combine like terms: 20 + -20 = 0
0 + 4x = 180 + -20
4x = 180 + -20
Combine like terms: 180 + -20 = 160
4x = 160
Divide each side by '4'.
x = 40
Simplifying
x = 40
