Answer:

[tex]x = 14[/tex]

[tex]y = -3[/tex]

Step-by-step explanation:

Given

[tex]2x + 8y =4[/tex]

[tex]x = -3y + 5[/tex]

Required

Solve

Substitute [tex]x = -3y + 5[/tex] in [tex]2x + 8y =4[/tex]

[tex]2(-3y + 5) + 8y =4[/tex]

Open bracket

[tex]-6y + 10 + 8y =4[/tex]

Collect like terms

[tex]-6y + 8y =4-10[/tex]

[tex]2y =-6[/tex]

Divide both sides by 2

[tex]y = -3[/tex]

Substitute [tex]y = -3[/tex] in [tex]x = -3y + 5[/tex]

[tex]x = -3 * -3 + 5[/tex]

[tex]x = 9+ 5[/tex]

[tex]x = 14[/tex]
