Find the value of x that makes the expression equivalent. (35 points)

7(8 - x); 56 - 21

x=3

Step-by-step explanation:

7(8-x)=56-21

Distribute the 7

7*8 -7x = 56-21

56 - 7x = 56-21

Since there is a 56 on each side , subtract 56 from both sides

56-56 - 7x = 56-56-21

-7x = -21

Divide each side by -7

-7x/-7 = -21/-7

x =3

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3
