To solve for x, we need to isolate it on one side of the equation.
5/8(x + 1/2) = 100
First, distribute the 5/8 to the terms inside the parentheses:
5/8 * x + 5/8 * 1/2 = 100
5/8 * x + 5/16 = 100
To eliminate the fraction, multiply both sides of the equation by the reciprocal of 5/8, which is 8/5:
8/5 * (5/8 * x + 5/16) = 8/5 * 100
On the left side, the 5/8 * 8/5 cancels out, leaving us with x + 5/16:
x + 5/16 = 800/5
Simplifying the right side:
x + 5/16 = 160
Next, subtract 5/16 from both sides of the equation to isolate x:
x = 160 - 5/16
To subtract the fractions, find a common denominator (16):
x = (160 * 16)/16 - 5/16
x = 2560/16 - 5/16
x = (2560 - 5)/16
x = 2555/16
So, the solution for x is 2555/16.
