x=23-4y

solve by substitution

Do you mean to put 9 in the place of x=23-4y (9x=23-4y)

**H**, Thursday, November 26, 2009 at 11:53pmIt would look like this...9(23-4y)+7y=4

Then you simplify

9*23=207

9*-4y=-36y

so you now have

207-36y+4y

Combine like terms

-36y+4y=-32

-32y=4

Finally you divide

the end reslut is y=-8
