Question

solve the system by the substituion method
y=-5x-7
5x-2y=-1

Answer 1

from the first equation, put -5x-7 in place of y

Answer 2

If \(y=-5x-7\), then
\[5x-2y=-1\]\[\Leftrightarrow5x-2(-5x-7)=-1\]Solve for x!

Answer 3

5x-2(-5x-7)=-1
15x=-15
x=-1
y=-2

Answer 4

i get how you got x but how is y-2

Answer 5

it is give, y=-5x-7
put the value of x in this equation, u will get y

Answer 6

it is given, sorry :)
