The equation for 3y + 3y = -1 is 3y + 3y = -1.

a) 4x+13y=40 b) 4x+3y=-40c) multiply b per(-1)=-4x-3y-40d) sum a and c: 4x+13y-4x-3y=40-(-40)=>10y=80 => y=8to find x replace y per its value in a or b and get x=-16
5y-2y= 3y+2 5y-2y-3y= 2 0y= 2
2x+3y=13 3x-y=3 x=2
y = 8

If you mean: 3y = 19+5 then the value of y is 8
Technically, the answer is probably YES, but it is a tautology and, therefore, adds no value.

"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=1y=2x+3y=2*1 + 3y=5
5x+3y
That depends on what the value of x is.
-2x plus 3y equals 1
If you mean 3y+24 = y-12 then the value of y works out as -18
The equation for 3y + 3y = -1 is 3y + 3y = -1.
