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

A

Step-by-step 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 =

)

3+11

14

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
