Multiple Choice For which equation is 6 a solution?

F. 鈥� 2y 鈥� 7 = 11 鈥� 5y

G. 11y 鈥� 32 =7y 鈥� 12

H. 18y 鈥� 16 =13y + 19

I. 鈥� 7y 鈥� 24 = 鈥� 8 鈥� 9y

Short Answer

Expert verified

The correct answer if F. -2y-7=11-5y

Step by step solution

01

Step-1 – Given

The given equations are:

-2y-7=11-5y,11y-32=7y-12,18y-16=13y+19,-7y-24=-8-9y

02

Step-2 – To determine

We have to identify the equation whose solution is 6.

03

Step-3 – Calculation

We check the equation of F first,

鈭�2y鈭�7=11鈭�5y鈭�2y鈭�7+7=11鈭�5y+7add7toeachside鈭�2y=18鈭�5y鈭�2y+5y=18鈭�5y+5yadd5ytoeachside3y=183y梅3=18梅3鈥勨赌�divideeachsideby3y=6

We got 6 as a solution of this equation. So, the equation -2y-7=11-5y has a solution equal to 6 Hence, the option F is the correct answer.
