4x+2x=18 4x + 2x = 18 4x+2x=18Solve the equation above for x x x.
Combine like terms on the left-hand side:
4x+2x=6x 4x + 2x = 6x 4x+2x=6x
The equation becomes:
6x=18 6x = 18 6x=18
Divide both sides by 6 to solve for x x x :
x=186 x = \frac{18}{6} x=618
Simplify the division:
x=3 x = 3 x=3
Thus, x=3 x = 3 x=3 is the solution to the equation.
