Answer:
The value of y when x equals 19 in 2x-5y = -28 is y = -2
Solution:
Given that the expression is 2x-5y = -28
We have to find the value of y when x equals 18
Substituting x = -19 in the above equation,
2(-19) – 5y = -28
On solving the terms inside the bracket, by multiplying 2 with -19 we get -38
-38-5y=-28
Cancelling the negative sign on both sides, we get
38+5y= 28
5y = -10
On dividing -10 by 5 we get -2.
y= -2
Hence the value of y when x equals 19 in 2x-5y = -28 is y = -2
