Question

appreciate the help!

Solve using substitution

8x-7y=-5
x-8y=-2

Answer 1

second equation solve for x via
\[x=8y-2\]

Answer 2

8(8y-2)-7y ?

Answer 3

yes

Answer 4

don't forget the =-5, gets important

Answer 5

then replace in first equation being careful with parentheses
\[8(8y-2)-7y=-5\]
\[64y-16-7y=-5\]
\[48y=-5+16\]
\[48y=11\]

Answer 6

oh mistake sorry

Answer 7

64-7=57

Answer 8

y=11/57 and subsitute in

Answer 9

\[8(8y-2)-7y=-5\]
\[64y-16-7y=-5\]
\[57y=-5+16\]
\[57y=11\]
\[y=\frac{11}{57}\]

Answer 10

looks like you got it!
