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
