Question
3\left(x-2\right)+4=19
Solve the equation
x=7
Evaluate
3\left(x-2\right)+4=19
Move the expression to the left side
3\left(x-2\right)+4-19=0
Subtract the numbers
3\left(x-2\right)-15=0
Calculate

Evaluate
3\left(x-2\right)-15
Expand the expression

Calculate
3\left(x-2\right)
Apply the distributive property
3x-3\times 2
Multiply the numbers
3x-6
3x-6-15
Subtract the numbers
3x-21
3x-21=0
Move the constant to the right-hand side and change its sign
3x=0+21
Removing 0 doesn't change the value,so remove it from the expression
3x=21
Divide both sides
\frac{3x}{3}=\frac{21}{3}
Divide the numbers
x=\frac{21}{3}
