How do you solve -4x-49y-80=0

x=

−49/4y−20

Step-by-step explanation:

Let's solve for x.

−4x−49y−80=0

Step 1: Add 49y to both sides.

−4x−49y−80+49y=0+49y

−4x−80=49y

Step 2: Add 80 to both sides.

−4x−80+80=49y+80

−4x=49y+80

Step 3: Divide both sides by -4.

−4x

−4

=

49y+80

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

a.

step-by-step explanation:
