Question

Combine like terms. Then, solve for x.
7 + 8x – 9 = 62
[?] + 8x = 62 (7 + 9 goes in the [?])
x = [?]

Answer 1

First, let's combine like terms on the left side of the equation:

7 + 8x - 9 can be simplified as follows:

7 - 9 = -2, so:

-2 + 8x = 62

Now, we rewrite the equation:

-2 + 8x = 62

Next, to isolate the term with x (8x), we'll add 2 to both sides of the equation:

8x = 62 + 2

8x = 64

Now, divide both sides by 8 to solve for x:

x = 64 / 8

x = 8

Thus, we have:

[?] = -2 (which comes from 7 + 9)
x = 8
