Question
Solve the equation
x=4
Evaluate
16−7(5−x)=9
Move the expression to the left side
16−7(5−x)−9=0
Subtract the numbers
7−7(5−x)=0
Calculate
More Steps

Evaluate
7−7(5−x)
Expand the expression
More Steps

Calculate
−7(5−x)
Apply the distributive property
−7×5−(−7x)
Multiply the numbers
−35−(−7x)
If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses
−35+7x
7−35+7x
Subtract the numbers
−28+7x
−28+7x=0
Move the constant to the right-hand side and change its sign
7x=0+28
Removing 0 doesn't change the value,so remove it from the expression
7x=28
Divide both sides
77x=728
Divide the numbers
x=728
