Respuesta :
You would have to plug it in ~ 5(3y-7)+2y=33, then you would multiply ~ 15y-35+2y=33, then you would simplify ~ 17y=68, then divide ~ y=4, then plug in y and multiply and simplify ~ x=3(4)-7 -- x=12-7 -- x=5. Answer~X=5 Y=4
x=-3y-7
5x+2y=33
Solve x = 3y-7 for x
Substitute 3y-7 for x in 5x +2y=33
5x+2y=33
5(3y-7)+2y=33
Simplify both sides of the equation
17y-35=33
Add 35 to both sides
17y-35+35=33+35
17y=68
Divide both sides by 17
17y/17=68/17
y=4
Substitute 4 for y in x =3y-7
x =3y-7
x =(3)(4)-7
Simplify both sides of the equation
x=5
Answer : x=5 and y=4
I hope that's help and have a great day !
