Question

. Solve for x 5x – 7 = 19 Give your answer as an 

Answer 1

5x - 7 = 19

Add 7 to both sides:

5x = 26

Divide both sides by 5:

x = 26/5

Answer 2

$5x - 7 = 19$

Move -7 to another side and become + 7. Whenever we move to another side, we change the sign/operator to opposite. Ergo, changing from plus to minus and multiply to divide.

$5x = 19 + 7 \\ 5x = 26$

We are at this part. Now to move 5 which is multiplying the x. So we move 5 from multiply to divide 26.

$x = \frac{26}{5}$

Ergo, the answer is x = 26/5
