For finding y-intercept we equalise x by zero

y = 3x+17

y =3(0)+17

y = 0+17

y = 17

y-intercept : (0,17)

Use the substitution method to solve. y=5−3x 5x−4y=−3

Vadim26 [7]

Well just substitute y (the first equation) into the second equation.
So
5x-4(5-3x)=-3
Then just solve the equation from there.
5x-20+12x=-3
17x=17
x=1
and if you need y, y=2
