Respuesta :
Y=-3+3x. You get this answer for y because you move all terms to the right that don’t contain y, and then you solve.
3x - y = 3
add y to both sides
3x = 3 + y
subtract 3 from both sides
3x - 3 = y
rewrite
y = 3x - 3
add y to both sides
3x = 3 + y
subtract 3 from both sides
3x - 3 = y
rewrite
y = 3x - 3
