Answer:
x = 20
Explanation:
Simplifying
1250 + 27.50x = 1400 + 20x
Solving
1250 + 27.50x = 1400 + 20x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-20x' to each side of the equation.
1250 + 27.50x + -20x = 1400 + 20x + -20x
Combine like terms: 27.50x + -20x = 7.5x
1250 + 7.5x = 1400 + 20x + -20x
Combine like terms: 20x + -20x = 0
1250 + 7.5x = 1400 + 0
1250 + 7.5x = 1400
Add '-1250' to each side of the equation.
1250 + -1250 + 7.5x = 1400 + -1250
Combine like terms: 1250 + -1250 = 0
0 + 7.5x = 1400 + -1250
7.5x = 1400 + -1250
Combine like terms: 1400 + -1250 = 150
7.5x = 150
Divide each side by '7.5'.
x = 20
Simplifying
x = 20
