It equals x+5y simplified
2a - 4y = 3a - 8a - 5y 7a = -ya = -(y/7)
They are: x = -2 and y = -1.
x + y = 10. Substitute x = 4y into this equation: 4y + y = 10 Combine like ters: 5y = 10 Divide through by 5: y = 2 Substitute this value of y in x = 4y ie x = 4*2 = 8.
One linear equation in two variables (x and y) cannot be solved.
It equals x+5y simplified
2a - 4y = 3a - 8a - 5y 7a = -ya = -(y/7)
They are: x = -2 and y = -1.
27 + y = 42 - 4y so 5y = 15 making y = 3 and x = 6
(6x - 5y) + (-3x - 4y) =6x - 5y - 3x - 4y =3x - 9y =3 (x - 3y)
x + y = 10. Substitute x = 4y into this equation: 4y + y = 10 Combine like ters: 5y = 10 Divide through by 5: y = 2 Substitute this value of y in x = 4y ie x = 4*2 = 8.
It works out that the solutions are: x = 3 and y = 2
x = 2, y = 3
It works out that: x = 3 and y = 2
4y + 10 = -18 4y = -28 y = -7
One linear equation in two variables (x and y) cannot be solved.
-8 - 5y = 12 - 9y -8 + 4y = 12 4y = 20 y = 20/4 or 5
