Question

3(5+x)>7x-1

Answer 1

15 +3x > 7x -1
15 + 1 > 7x - 3x
16 > 4x
16/4 > x
4 > x

Answer 2

First distribute the 3 into the parenthesis:

3(5 + x) > 7x - 1

15 + 3x > 7x - 1

Subtract 7x to both sides:

15 - 4x > -1

Subtract 15 to both sides:

-4x > -16

Divide -4 to both sides:

x < 4

Don't forget to switch the sign when dividing by a negative number!
