Answer:
x=2
Step-by-step explanation:
y=-x+2
y=3x−4
multiply the top by three so it matches the bottom so:
y=-3x+6
y=3x−4
then solve for y by adding the two equations together so:
y=2
then plug y=2 into any of the two original equations so:
2=-x+2 or 2=3x-4
then solve for x (i will be solving the second one)
2=3x-4
add 4 to both sides
6=3x
divide by 3 on both sides so:
x=2
Answer:
Well you can solve this a lot of ways but this one is easy with substitution. The answer is (7/6,1/2)
Step-by-step explanation:
Make one of the equations equal to x -
y=-x+2 can be converted to x=-y+2
Then substitute that into the second equation.
y=3(-y+2)-4
then simplify
y=-3y+6-4
y=-3y+2
add 3y to both sides to eliminate the -3y
4y=2
then simplify again.
y=1/2
Last step: plug in 1/2 as y in either equation and simplify to get x.
1/2=3x-4
You should get x=7/6
the answer is (7/6,1/2)
