Question
Solve the equation
x=27
Alternative Form
x=3.5
Evaluate
7−5(x−2)=x−4
Move the expression to the left side
7−5(x−2)−(x−4)=0
Subtract the terms
More Steps
Evaluate
7−5(x−2)−(x−4)
If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses
7−5(x−2)−x+4
Add the numbers
11−5(x−2)−x
11−5(x−2)−x=0
Calculate

Evaluate
11−5(x−2)−x
Expand the expression
More Steps
Calculate
−5(x−2)
Apply the distributive property
−5x−(−5×2)
Multiply the numbers
−5x−(−10)
If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses
−5x+10
11−5x+10−x

Evaluate
−5x−x
Collect like terms by calculating the sum or difference of their coefficients
(−5−1)x
Subtract the numbers
−6x
21−6x
21−6x=0
Move the constant to the right-hand side and change its sign
−6x=0−21
Removing 0 doesn't change the value,so remove it from the expression
−6x=−21
Change the signs on both sides of the equation
6x=21
Divide both sides
66x=621
Divide the numbers
x=621
Solution
