Question

show work for 4x+3y=3;x=32-7y

Answer 1

since you already have a defined x: \(x=32-7y\) it would probably be quickest to plug that in, as such: \[4(32-7y)+3y=3\] solve that to find y, and then use that value to determine x

Answer 2

substitute x into x
4(32-7y) + 3y=
then do distributive property 4 x 32 = 128 and 4 x -7y = -28y
128-28y+3y=
then combine like terms -28y + 3y = -25y
128-25y=3
do the opposite orderation 3-128=-125
-25y=-125
do opposite -125/-25
y=5
now substitute y into x equation
32-7(5)=125=x
4(125) + 3(5)=3
500+15=3
