Explanation:
solve for y in both equations
subtract 3x from both sides
-y=4-3x
multiply the equation by -1
y=-1(4-3x)
subtract both sides by x
2y=6-x
divide both sides by 2
y=(6-x)/2
- Now set the y values equal to each other
-1(3x-4)=(6-x)/2
-3x+4=(6-x)/2
multiply both sides by 2
-6x+8=6-x
add 6x to both sides and subtract 6 to both sides
2=x
put 2 back into x for y=(6-x)/2
y=2
Hope that helps :)
