They're called variables (this sounds like vary because the number that a letter could represent varies) so when i say 1 + x = 3 it is saying that they don't know the value of x yet but of course you can solve that by subtracting 1 from 3 which is 2

Solve the second equation.<br>2x - y = 8<br>First, solve for (-y).<br>--y =<br>​
kicyunya [14]

Answer:

-y=-2x+8\\y=2x-8

Step-by-step explanation:

To solve, first subtract 2x from both sides.

2x-y=8\\-y=-2x+8

You appear to want the solution for -y, so I've included it. Given that you also want the solution for y, divide both sides by -1.

-y=-2x+8\\y=2x-8

= 3 + 2 ⋅ [(15) + 8]

= 3 + 2 ⋅ [23]

= 3 + 46

= 49
