You have 2 equations and 2 unknowns so you can solve
2x-3y = -11
y = 4x -3
2x - 3y = -11
-4x + y = -3
multiply 1st equation by 2 both sides:
4x-6y = -22
-4x + y = -3
add:
-5y = -25
y = 5
substitute y = 5 into either equation:
-4x+y = -3
-4x +5 = -3
-4x = -8
x = 2

1). y = 12). y = -4x3). y = -12xA "solution" is a pair of numbers ... one for 'x' and one for 'y' ... that makes the statements true.There is no solution for the group of all three equations.The solution for #1 and #2 taken together is (-1/4 , 1).The solution for #1 and #3 taken together is (-1/12 , 1).The solution for #2 and #3 taken together is (0, 0).
It is an equation of a straight line.
2x + y = 3 and y = 5x - 11 1) Plug the second equation for y into the first 2) 2x + (5x - 11) = 3 3) Solve for X 4) 7x = 14 5) x = 2 6) Plug X into either equation to get Y 7) 2(2) + y = 3 8) y = -1
If "equations-" is intended to be "equations", the answer is y = -2. If the first equation is meant to start with -3x, the answer is y = 0.2
