To know this, we can either test the claim by plugging in 2 for X, or we can solve for X and see if X = 2 is a possible answer. To solve for X, we want to follow these steps.

Simplify both sides of the equation by first combining like variables, giving us:

26x + 4 = 30x - 3

Then, we move all terms with X to one side, and those without X to the other, isolating X:

26x + 4 = 30x - 3

-26x -26x

4 = 4x - 3

+3 +3

7 = 4x

Finally, we divide by the coefficient in front of x to find that x = 7/4, which is not equal to 2. Therefore, Chad is incorrect.

Alternatively, we could plug in 2 for X and see if the two sides are equal. Here we get:

26 (2) + 4 = 30 (2) - 3

52 + 4 = 60 - 3

56 = 57

The two sides of the equation are not equal, so Chad is incorrect in asserting that x = 2.
