Question

If 2(2y+9)=4, then y=______

Answer 1

Answer:

-3.5

Step-by-step explanation:

4y+18=4

4y=4-18

4y=-14

y=-14/4

y=-7/2

y=-3.5

Answer 2

Linear Equations -

We need to find the value of y

2(2y+9) = 4

4y + 18 (by multiplying with 2) = 4

4y = 4 - 18 (by transposing) [P.S - when sides are changed , signs are changed too]

4y = -14

y = -14/4 (by transposing)

y = -7/2

y = - 3.5 (Converting to decimal)
