I can't figure out how to do this problem. Could somebody help me?

"Find the value of a that makes the ordered pair a solution of the equation.

1. -4x - 3y = 17; (a+ 1,5)

Respuesta :

start by plugging in the value you already have, in this case, 5 for y.

-4x-3(5)=17

-4x-15=17

-4x=32

x=-8

however, since a is a+1, a would be 7 (making x 8)

also plz tell me if i read this wrong and it’s actually 1,5 rather than a+1 and 5 cause if i did i’m so sorry lol.
