Question

use a table to find the solution of the system
y=7-x
y=x+1

Answer 1

can you rewrite the second equation so that x is isolated?

Answer 2

no

Answer 3

ok, let me help. so since you have y=7-x, you want to carry the x over to the left and the y over to the right.

add x to both sides and subtract y from both sides getting: x=-y+7

Answer 4

thats the answer?

Answer 5

no

Answer 6

but you plug it into the second equation

Answer 7

try plugging x=-y+7 into y=x+1

Answer 8

what is it

Answer 9

can you try it?
