Question

The product of 8 and the sum of a number and 12 is 240

Answer 1

18

Explanation:

Let the number be 'x'

Sum of 'x' and 12 = x +12

The product of 8 and the sum of a number and 12 = 8* (x +12)

= 8*x + 8*12

= 8x + 96

8x + 96 = 240

Subtract 96 from both sides

8x + 9 6 - 96 = 240 - 96

8x = 144

Divide both sides by 8

x = 144/8

x = 18
