y= 3x - 4
y= -2x + 1
Since both equations are equal to y, it is possible to set both equations equal to each other: 3x - 4 = -2x + 1
Now, move the x variables to one side and the numbers to the other.
Add 2x to both sides:
5x - 4 = 1
Add 4 to both sides:
5x = 5
Divide both sides by 5:
x = 1
x = 4 and y = 0
the answer
Solve this system of equations. 5x+3y+z=-29 x-3y+2z=23 14x-2y+3z=-18 Write the solution as an ordered triple.
x = -1.2, y = -3
a=5: c=4
To solve for two unknowns (x and y) it is necessary to have two independent equations.
x = 6 and y = -2
(0,7)
To solve an equation with three unknowns, x, y and z, you require 3 independent equations.

When talking about a "system of equations", you would normally expect to have two or more equations. It is quite common to have as many equations as you have variables, so in this case you should have two equations.
