3x + 9y = -42 -3x + 2y = -2 the solution to the system is

Hi there,

The solution for y= -4 and for x it is -2. You can also write it as (-2,-4). If you need all the steps let me know. I can show you. Otherwise, Hope it helps.

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

step-by-step explanation:

2*5=10

4*15=60

60+10=
