Question
Solve the equation
x=3
Evaluate
6x+2(x+3)=30
Move the expression to the left side
6x+2(x+3)−30=0
Calculate the sum or difference
More Steps

Evaluate
6x+2(x+3)−30
Expand the expression
More Steps

Calculate
2(x+3)
Apply the distributive property
2x+2×3
Multiply the numbers
2x+6
6x+2x+6−30
Add the terms
More Steps

Evaluate
6x+2x
Collect like terms by calculating the sum or difference of their coefficients
(6+2)x
Add the numbers
8x
8x+6−30
Subtract the numbers
8x−24
8x−24=0
Move the constant to the right-hand side and change its sign
8x=0+24
Removing 0 doesn't change the value,so remove it from the expression
8x=24
Divide both sides
88x=824
Divide the numbers
x=824
