Solving Linear Equations Unit Test Solve for x 20 = 5 - 3/8 * x (1 point )

Answer 1

To solve for x in the equation 20 = 5 - 3/8 * x, first we need to isolate x on one side of the equation.

First, we'll get rid of the fraction by multiplying both sides of the equation by 8:
20 * 8 = 5 * 8 - 3x
160 = 40 - 3x

Next, we'll isolate the x term by subtracting 40 from both sides of the equation:
160 - 40 = -3x
120 = -3x

Finally, we'll solve for x by dividing both sides of the equation by -3:
x = 120 / -3
x = -40

Therefore, the solution to the equation is x = -40.
