Answer:

38.2, or 38 1/2

Step-by-step explanation:

Steps for Solving Linear Equation:

4=51.75−1.25x

Swap sides so that all variable terms are on the left hand side.

51.75−1.25x=4

Subtract 51.75 from both sides.

−1.25x=4−51.75

Subtract 51.75 from 4 to get −47.75.

−1.25x=−47.75

Divide both sides by −1.25.

x=−1.25−47.75​

Expand −1.25−47.75​≈38.2 by multiplying both numerator and the denominator by 100.

x=−125−4775​

Reduce the fraction −125−4775​≈38.2 to lowest terms by extracting and canceling out −25.

x=5191​
