✔ 最佳答案
y + 2x + 2 = 4y = - 2x - 2 + 4
y = - 2x + 2
Answer: y = - 2x + 2 OR y = - 2(x - 2)

Solve for x.
y + 2x + 2 = 4
2x = 4 - y - 2
2x = -y + 4 - 2
x = (-y + 2)/2
x = -y/2 + 2/2
x = -y/2 + 1
Solve for y.
y + 2x + 2 = 4
y = -2x - 2 + 4
y = -2x + 2
y + 2x + 2 = 4
2x = 4 - y - 2
2x = -y + 4 - 2
x = (-y + 2)/2
x = -y/2 + 2/2
x = -y/2 + 1
Solve for y.
y + 2x + 2 = 4
y = -2x - 2 + 4
y = -2x + 2

What do you mean by "solve" ?
Making y the subject :-
y = - 2 x + 2
Making y the subject :-

y + 2x + 2 = 4
y + 2x + 2 -2 = 4 - 2
y + 2x = 2
y + 2x - 2x = -2x + 2
y + 2x = -2x + 2
y + 2x + 2 -2 = 4 - 2
y + 2x = 2
y + 2x - 2x = -2x + 2
y + 2x = -2x + 2
