Question
Solve the equation
x=17
Evaluate
5x−5(30−x)=20
Move the expression to the left side
5x−5(30−x)−20=0
Calculate
More Steps
Evaluate
5x−5(30−x)−20
Expand the expression
More Steps
Calculate
−5(30−x)
Apply the distributive property
−5×30−(−5x)
Multiply the numbers
−150−(−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
−150+5x
5x−150+5x−20
Add the terms
More Steps
Evaluate
5x+5x
Collect like terms by calculating the sum or difference of their coefficients
(5+5)x
Add the numbers
10x
10x−150−20
Subtract the numbers
10x−170
10x−170=0
Move the constant to the right-hand side and change its sign
10x=0+170
Removing 0 doesn't change the value,so remove it from the expression
10x=170
Divide both sides
1010x=10170
Divide the numbers
x=10170
