what is 4(x-1)=28

Question

enter your answer as an equation that shows the value of the variables (like s=2/3 or 4=w)

Answer 1

4(x-1)=28

First you need to multiply everything that is in parenthesis. 

4*x =4x ; 4 *-1 = -4

New equation 4x-4=28

Next add 4 to both sides of the equation.

4x-4+4= 28 + 4

New equation : 4x=32

Finally divide both sides by 4  to find out what (x) is. 

4x/4 = 32/4

Your Answer : x = 8. 

 

Answer 2

x = 8

To solve, first distribute the left side of the equation to get:

4x - 4 = 28

Next, add 4 to both sides of the equation:

4x - 4 + 4 = 28 + 4

4x = 32

Finally, divide both sides by 4:

4x/4 = 32/4

x = 8
