Answer:

c=-6

Step-by-step explanation:

I used a calculator and paper and a pencil d---------b yeah :D yr welcome

Ok, so you would want to simplify both sides of the equation

(-1/3)(-12) + (1/3)(-12c)=-20 (here you distribute)

4+4c=-20

Then, subtract 4 from both sides

4c+4-4=-20-4

4c=-24

Then divide both sides by 4

4c/4=-24/4

c=-6

Answer:

1.) y=3x-7

2.) 2=5x-y

3.) y=-4-2x

4.) 1=3/4x+y

5.) y=4x+8

6.) 9=3/4x+8

7.) 9=y+x

8.) y=-2/6x+2

9.) 5=-2/3x+y

Step-by-step explanation:

Standard form is Ax=By=C and Slope form is y-mx+b

for all of the equations fiqure out which is standard and which is slope, 3x-y=7 is standard and just switch it to slope ie:

3x-y=7

+7 -7

3x-7=y

then switch around so y is in the front and vice versa, also divde any y or C by negative 1 if the answer is negative or if there is a number in front of it like in 9, and 8
