Question

Five times a number minus 7 is thirteen

Answer 1

5n-7=13 n= 4 so the number is 4

Answer 2

x = 4

Steps:

5x - 7 = 13

First add 7 to both sides

5x = 20

Next divide the coefficient, 5, on both sides

x = 4

Check:

Substitute 4 for x

5x - 7 = 13

5(4) - 7 = 13

Solve

20 - 7 = 13

13 = 13
