Given:
1/5(25x-75)+9=1/4(8x+36)
Simplify the expression:
Solution:
Distribute1/5 and ¼ to the corresponding values inside the parenthesis.
1/5(25x-75)+9=1/4(8x+36)
5x - 25 + 9 = 2x + 9
Transpose 2x + 9 on the opposite side of the equation and combine like terms. Remember when transposing a number, the sign changes.
5x -25 + 9 - 2x - 9 = 0
3x -25 = 0
In order to determine the value of x, transpose -25 on the other side of the equation and divide both sides by 3.
3x = 25
x = 25/3 or 8.333
