Question

What is the solution of this equation?

7y – 4 = 9y + 13 – 4y

A. y = 17/2
B. y =9/2
C. y=17/12
D. y= 3/4

Answer 1

A

Explanation:

Given

7y - 4 = 9y + 13 - 4y ( simplify right side )

7y - 4 = 5y + 13 ( subtract 5y from both sides )

2y - 4 = 13 ( add 4 to both sides )

2y = 17 ( divide both sides by 2 )

y =
`(17)/(2)`
