I don’t know what the answer is
Answer:
Y=2
X=-1
Step-by-step explanation:
In substitution method we have to put the value of one variable from first equation to the another given equation.
here equation are
x=3y-7 ......a
4x+3y=2 .......b
put the value of x from equation first into the second equation
so, 4(3y-7)+3y=2
(12y-28)+3y=2
15y-28=2
15y=2+28
15y=30
or y=30/2=2
now put this y value in equation a
x=3(2)-7
x=6-7=-1
hence y=2 and x= -1

Answer:
y=-x-6
Step-by-step explanation:
y-y1=m(x-x1)
y-(-5)=-1(x-(-1))
y+5=-(x+1)
y=-x-1-5
y=-x-6
