Given the equation:

3x + 7 =13

Determine the operations to solve for x.

Solution:

In order to solve for x, we simply need to transpose 7 on the other side of the equation, hence we must take note that when transposing a number, the sign changes.

3x + 7 = 13

3x = 13 - 7

3x = 6

Divide both sides by 3 in order to get the value of x.

3x/3 =6/3

x = 2

Final answer:
x =2
