Question

y + 2x = 5;x = -1,0,3 find the value of y for each value of x

Answer 1

y=7,5,-1 respectively

Answer 2

You need to do some basic arithmetic. The problem gives you a value for x. You just need to put the value of x.

First, you need to know this:
y + 2x = 5
So:
y + 2x - 2x = 5 -2x
y = 5 - 2x

If x = -1:
y = 5 - 2 (-1) = 5 + 2 = 7

Try the next one yourself

Answer 3

so the next one is 3x - 5y =9; x =-1,0,1

Answer 4

so whats the first step

Answer 5

First of all, you want to now the value of y. So the first step is to have y alone
