This might be wrong, but you need to get x be itself on the left side and then after you do that, the x on both sides will cancel. Whenever you try to subtract one x from the other it will cancel them. So technically that's all you can do.

Answer:
{x,y} = {2,9}
Step-by-step explanation:
Solve equation [2] for the variable y
[2] 2y = -6x + 30
[2] y = -3x + 15
// Plug this in for variable y in equation [1]
[1] 3x + 2•(-3x+15) = 24
[1] -3x = -6
// Solve equation [1] for the variable x
[1] 3x = 6
[1] x = 2
// By now we know this much :
x = 2
y = -3x+15
// Use the x value to solve for y
y = -3(2)+15 = 9
Answer:
2x +5(y+3)
Step-by-step explanation:
this depends on what you want
x+y+x+y+3(y+5)
expanding this, we have;
2x +2y +3y+15
2x +5y +15
2x +5(y+3)
