The solution to the system of equations x-9y=65 and 6y-8x=8 is (-7,-8).The easiest way to do substitution is to find the variable that can be isolated the easiest, that is, get either x or y alone. The easiest variable to get alone is the x in the first equation. All you need to do is add 9y to each side. Working through the substitution:The system of equations:x-9y=656y-8x=8Step 1: Get a variable alonex-9y=65x-9y+9y=65+9yx=9y+65Step 2: Substitute into the other equation6y-8x=86y-8(9y+65)=8 → Expand6y-72y-520=8 → Combine like terms-66y-520=8 → Add 520 to both sides-66y=8+520 → Simplify-66y=528 → Divide by -66 to find yy=-8Step 3: Substitute y=-8 into the first equationx=9y+65x=9(-8)+65x=-72+65x=-7The solution to the system of equations x-9y=65 and 6y-8x=8 is (-7,-8).

9y^2

9y - 4x

Reorder the terms: -5 + 42y + 27y2 Factor a trinomial. (-5 + -3y)(1 + -9y)

(-y+4)+ (9y-6) (9y-y) + (4-6) 8y - 2

The variables have no known values and as an expression it is: 5x+9y+5

2x + 3y + 4x + 9y = 2x + 4x + 3y + 9y = 6x + 12y which can be simplified to 6(x + 2y)
