Question

5 subtracted from 3 times a number x gives 7.

​

Answer 1

3x-5=7

3x=7+5

x=12/3

x = 4

Answer 2

Explanation:

3 times a number x: 3*x = 3x

5 subtracted from 3x = 3x - 5

Equation: 3x - 5 = 7

Solution:

Add 5 to both sides

3x - 5 + 5 = 7 + 5

3x = 12

Divide both sides by 3

3x/3 = 12/3

x = 4
