It can be simplified to: -3y-5 as an algebraic expression
It is 3y + 5.
4y -5
x = 5, y = -1
We will see. 3X + 2Y = 15 6X + 4Y = 30 I do not like the look of elimination, so substitution 3X + 2Y = 15 3X = 15 - 2Y X = 5 - 2/3Y -------------- 6(5 - 2/3Y) + 4Y = 30 30 - 12/3Y = 30 30 - 4Y = 30 this is inconsistent in approach 3(5 - 2/3Y) + 2Y = 15 15 - 15/3Y = 15 another bad approach, try elimination to show inconsistency - 2(3X + 2Y = 15) 6X + 4Y + 30 -6X - 4Y = - 30 6X + 4Y = 30 I think it is safe to say these systems of equations are inconsistent --------------------
I don't know whether it's y^2-3y+2+3y-4y-5 or 2y-3y+2+3y-4y-5, so I'll do both.y^2-3y+2+3y-4y-5y^2+(-3y+3y-4y)+(2-5); group them togethery^2+(-4y)+(-3)y2-4y-3OR2y-3y+2+3y-4y-5(2y-3y+3y-4y)+(2-5); group them together(-2y)+(-3)-2y-3
4y + 4 = 3y - 5 y = -9
It can be simplified to: -3y-5 as an algebraic expression
It is 3y + 5.
4y -5
It is: 3y-6
"3y + 4y = 19" is a mathematical sentence involving one unknown, y. If you wanted it solved (ie you meant to ask; "What is y in 3y plus 4 y equals 19"), then: 3y + 4y = 19 → (3 + 4)y = 19 → 7y = 19 → y = 19/7 = 2 5/7 ≈ 2.71
x = 5, y = -1

y = 3.6 (18/5)
