Verified Answer :

If y = -2, then just put in -2 for every y in the other equation to solve for x, 

\(4x - 3(-2) = 18\)

then solve for x\

\(4x + 6 = 18\)

\(4x = 12\)

\(x=3\)

Then write the answer as (3,-2)

Simple...

you have: y=-2 and 4x-3y=18

To solve this substitute y into the equation-->>

4x-3(-2)=18

(Now solve like any other problem..)

4x-3(-2)=18

4x+6=18

4x+6=18
    -6    -6

4x=12

x=3

Now plug that back into the equation to make sure it's correct-->>

4(3)-3(-2)=18

12+6=18

18=18

Your point of intersection (3,-2).

Thus, your answer.
