Given the equation:
-3x + 7x = -10
Solve the equation.
Solution:
In order to solve the equation, we simply need to combine similar terms.
-3x + 7x = 10
4x = 10
Transpose 10 to the other side of the equation, hence it must be taken to note that in transposing a number, the sign changes.
= 4x - 10
If we are asked to solve for the value of x, then we need to divide 4 on both sides of the equation.
4x/4 = 10/4
x = 10/4
x = 5/2
Final answer:
Simplified form = 4x - 10
x = 5/2
