Question

pls solve the equation fast
ans also given but the full process don't know pls help​

Answer 1

Answer:

6y-4-8y +20=9

-2y -4 +20=9

-2y +16 = 9

-2y = 9-16

-2y = -3

y = 3/2

Answer 2

Step-by-step explanation:

$2(3y-2)-4(2y-5)=9 \\ \rightarrow 6y-4-8y+20=9 \\ \rightarrow -2y+16=9 \\ \rightarrow 2y=7 \\ \rightarrow y=\frac{7}{2}=3\frac{1}{2}$
