Please help i can’t do this

A = -3, B = 1, and C = 19 OR A = 3, B= -1, C = -19 (look at the explaination)

Step-by-step explanation:

You will need to expand the equation given to you.

y-7 = 3(x+4)

y-7=3x+12

y- 7 + 7 = 3x + 12 +7

y = 3x + 19

-3x + y = 19

Therefore, A = -3, B = 1, and C = 19

But, you can also write it as:

y = 3x + 19

3x - y = -19

A = 3, B= -1, C = -19

So, I don't know what your teacher wants but both answers should be right.

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
