Question

Please solve question 8 and 9​

Answer 1

8th Answer :

1 Multiply both sides by 6 (the LCM of 3,2).

2(y+1)-3(y-1)=2(1+2y)

2 Expand.

2y+2-3y+3=2+4y

3 Simplify 2y+2-3y+3 to -y+5

-y+5=2+4y

4 Regroup terms.

5-y=2+4y

5 Add y to both sides.

5=2+4y+y

6 Simplify 2+4y+y to 2+5y.

5=2+5y5=2+5y

7 Subtract 2 from both sides.

5-2=5y

8 Simplify 5-2 to 3

3=5y

9 Divide both sides by 5.

3/5=y

10 Switch sides.

y=3/5
