4x+9y=9; x-3y=-6
elimination method

x=9, y=5. (9, 5).

Step-by-step explanation:

-4x+9y=9

x-3y=-6

x=3y+(-6)

x=3y-6

-4(3y-6)+9y=9

-12y+24+9y=9

-3y=9-24

-3y=-15

3y=15

y=15/3

y=5

x-3(5)=-6

x-15=-6

x=-6+15

x=9

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

hi there!

the answer to this question is d: 35

step-by-step explanation:

5 to the power of 2 is 25
