Answer:
x=10
Explanation:
Simplifying
1.5x + 3 = 18
Reorder the terms:
3 + 1.5x = 18
Solving
3 + 1.5x = 18
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3' to each side of the equation.
3 + -3 + 1.5x = 18 + -3
Combine like terms: 3 + -3 = 0
0 + 1.5x = 18 + -3
1.5x = 18 + -3
Combine like terms: 18 + -3 = 15
1.5x = 15
Divide each side by '1.5'.
x = 10
Simplifying
x = 10
