Question

5x+3(x-4)=60

explain please

Answer 1

Expand

5x + 3x - 12 = 60

Simplify 5x + 3x - 12 to 8x - 12

8x - 12 = 60

Add 12 to both sides

8x = 60 + 12

Simplify 60 + 12 to 72

8x = 72

Divide both sides by 8

x = 72/8

Simplify 72/8 to 9

x = 9

Answer 2

x=9

Explanation:

5x+3(x-4)=60

Distribute the 3

5x+3*x -3*4 = 60

5x+3x-12 = 60

Combine like terms

8x -12 =60

Add 12 to each side

8x-12 +12 = 60 +12

8x = 72

Divide by 8

8x/8 = 72/8

x = 9
