Question
Solve the equation
x=7
Evaluate
18−5(9−x)=8
Move the expression to the left side
18−5(9−x)−8=0
Subtract the numbers
10−5(9−x)=0
Calculate
More Steps

Evaluate
10−5(9−x)
Expand the expression
More Steps

Calculate
−5(9−x)
Apply the distributive property
−5×9−(−5x)
Multiply the numbers
−45−(−5x)
If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses
−45+5x
10−45+5x
Subtract the numbers
−35+5x
−35+5x=0
Move the constant to the right-hand side and change its sign
5x=0+35
Removing 0 doesn't change the value,so remove it from the expression
5x=35
Divide both sides
55x=535
Divide the numbers
x=535
