Given the numerical equation:
3x + 12 =7x - 18
Solve for x.
Solution:
In order to solve for x, we simply need to transpose 3x and 18 on the opposite sides of the equation, hence in transposing a number the sign changes.
3x + 12 = 7x - 18
12 + 18 = 7x + 3x
10x = 30
Divide both sides by 10 in order to find the value of x.
x = 3
Final answer:
x = 3
