Question

Solve the following equation: (7y +8) +7= 8

Sum

Solution

(7y +8) +7= 8

⇒ `("7y" + 8)/7 = 8`

⇒ `("7y" + 8)/7 xx 7 = 8 xx 7`  ...(Multiplying by 7)

⇒ 7y + 8 = 56

⇒ 7y + 8 - 8 - 56 - 8  ...(Subtracting 8 from both sides)

⇒ 7y = 48

⇒ `"7y"/7 = 48/7`   ..(Dividing by 7)

⇒ y = `48/7 = 6 6/7`
