Question

Is X = 4 the solution to the equation 3%−7=x+1?
a. True
b. False

Answer 1

By substituting X = 4 into the equation 3X - 7 = X + 1, and performing the arithmetic which results in 5 = 5, we confirm that X = 4 is the correct solution, making the statement True.

Step-by-step explanation:

The question asks if X = 4 is the solution to the equation 3X − 7 = X + 1.

This question is a True or False problem which requires us to substitute X = 4 into the equation and check its validity.

To solve this equation, follow these steps:

1. Substitute X = 4 into the equation: 3(4) − 7 = 4 + 1.
2. Perform the arithmetic: 12 − 7 = 4 + 1.
3. Simplify both sides: 5 = 5.

Since both sides of the equation are equal after the substitution, the statement is True.
