Question
Solve the equation
x=11
Evaluate
8x−4(15−x)=72
Move the expression to the left side
8x−4(15−x)−72=0
Calculate
More Steps
Evaluate
8x−4(15−x)−72
Expand the expression
More Steps
Calculate
−4(15−x)
Apply the distributive property
−4×15−(−4x)
Multiply the numbers
−60−(−4x)
If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses
−60+4x
8x−60+4x−72
Add the terms
More Steps
Evaluate
8x+4x
Collect like terms by calculating the sum or difference of their coefficients
(8+4)x
Add the numbers
12x
12x−60−72
Subtract the numbers
12x−132
12x−132=0
Move the constant to the right-hand side and change its sign
12x=0+132
Removing 0 doesn't change the value,so remove it from the expression
12x=132
Divide both sides
1212x=12132
Divide the numbers
x=12132
