Question

Solve 12(x - 1) = 40

Answer 1

Answer:

x = 13/3

Step-by-step explanation:

12(x - 1) = 40

Distribute

12x -12 = 40

Add 12 to each side

12x-12+12 = 40+12

12x = 52

Divide each side by 12

12x/12 =52/12

x =13/3

Answer 2

Answer:

around 2.67 (decimal form)

$\frac{8}{3 }$

Step-by-step explanation:

12( x - 1 ) = 40 (given)

12x - 12 = 40 (distribute)

12x - 12 + 12 = 40 + 12 (add 12 both sides)

12x = 40 + 12 (cancel 12 left side)

52 (combine like terms)

12x = 52/12 (divide 12 both side)

x = 8/3 (answer)

Around 2.67 just in case questions ask for roundings...
