Answer:
1) y=4-2x
2) y=3x-1
3) x=10-5y
Step-by-step explanation:
for number 1)
2x+y=4
find "y" in terms of "x"
subtract 2x from both side of the equation
to eliminate 2x from the left side.
2x+y-2x=4-2x
now, only "y" is left on the left side
y=4-2x
this is the answer.
Same proccess on the other question.
but make sure "y" or "x" is positive (depends on what is requured)
I hope it helps.
