Solve 20 = 5 - 3/8x

Answer 1

To solve for x, first multiply both sides by 8 to get rid of the fraction:

8(20) = 8(5) - 3x
160 = 40 - 3x

Next, isolate the term with x by subtracting 40 from both sides:

160 - 40 = 40 - 40 - 3x
120 = -3x

Finally, divide by -3 to solve for x:

x = 120 / -3
x = -40

Therefore, the solution to the equation 20 = 5 - 3/8x is x = -40.
