Answer 3

Let's solve each equation step by step:

A.) -4x = 32

To solve for x, we want to isolate x on one side of the equation. We can do this by performing the following steps:

1. Add 4x to both sides of the equation to get rid of the -4x on the left side: -4x + 4x = 32 + 4x 0 = 32 + 4x

2. Subtract 32 from both sides of the equation to isolate 4x on the right side: 0 - 32 = 32 + 4x - 32 -32 = 4x

3. Divide both sides of the equation by 4 to solve for x: -32 / 4 = 4x / 4 -8 = x

So the solution for equation A is x = -8.

B.) 2(7x - 7) = 7(2x - 3) + 7

To solve this equation, we need to apply the distributive property and simplify the expression:

1. Distribute the 2 and 7 on the left and right side, respectively: 14x - 14 = 14x - 21 + 7

2. Combine like terms on the right side: 14x - 14 = 14x - 14

At this point, we can see that both sides of the equation are the same. This means that the equation is an identity, and it is true for all values of x. Therefore, this equation has infinitely many solutions, and any value of x would satisfy the equation.

So the solution for equation B is x can be any real number.
