I don’t know which boxes to put into the answer. I can only use two of them. It’s a timed test if anyone can answer quick enough

10+10+100000000000+1222762766264827634876742684736274672346726385762756276592659826582658238954747457457457474747 x 1525353533446745745747547

Step-by-step explanation:

2nd goes to 1st box

5th goes to 2nd box

Step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
