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

What is the y-intercept of the line y equals 5x-11?
16
What is the solution for y equals 1 y equals -4x and y equals -12x?
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).
What is x plus y equals 11?
It is an equation of a straight line.
How do you solve each system by substitution 2x plus y equals 3 and y equals 5x-11?
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
What is the value of the y variable in the solution to the following system of equations- 3x - 6y equals 3 7x - 5y equals -11?
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
What is the slope of line with the equation 2x 3y plus 6 equals 0?
Put the equation in this form: y=mx+b. Then m will be the slope. 2x3y+6=0 2x3y=-6 3y=-6/2x y=-2/2x y=-1/x This equation does not describe a straight line, but rather, it describes a curve.
How do you factor this. x2y2 plus 2x3y?
x^2y(2x + y)
What is the answer to y plus 15 equals 11?
If: y+15 = 11 Then: y = -4
What is 6-y equals 17x?
6-y equals 17x = -11
When Y equals 48 and w equals 4 what is y when w equals 11?
You can set this problem up like this: 48/4 = y/11 Cross multiply 48*11 = 4y 528 = 4y 528 divided by 4 = 132 So when w equals 11 y equals 132
