Answer:

x = 3,y = -2

Step-by-step explanation:

Given data:

Y= -2

4x -3y=18

Solve:

Substitute the given y-value into 4x−3y=18 and solve for x

Since, y = -2,

[tex]4x-3(-2)=18[/tex]

[tex]4x+6=18[/tex]

[tex]4x+6-6=18-6[/tex]

[tex]4x=12[/tex]

[tex]\frac{4x}{4}=\frac{12}{4}[/tex]

[tex]x = 3[/tex]

The solution to the system of equations is x = 3, y = -2
