Which equations are true?
Vlad [161]

Answer:

Step-by-step explanation:

1)4.5m+4.7=20m+47

4.5m-20m=47-4.7

-15.5m=42.2

m=-2.72

2)14+21w=7(2+3w)

  41+21w=14+21w

   21w-21w=14-41

3)49r+35=7(7r+35)

  49r+35=49r+245

 49r-49r=245-35

4)9(8h-3)=72h-27

  72h-27=72h-27

   72h-72h=-27+27

5)5.2+5.3t=10+15t

   5.3t-15t=10-5.2

    -9.7t=4.8

      t=4.8/-9.7

      t=0.49

6)6f+3.111=18f-33

  6f-18f=-33-3.111

  -12f=-36.111

     f=-36.111/-12

     f=3.01

Select the ordered pair that is the solution of this equation: -7x – 4y = 6
Olegator [25]
Its just a matter of subbing

-7x - 4y = 6....subbing in (-2,2)...x = -2 and y = 2
-7(-2) - 4(2) = 6
14 - 8 = 6
6 = 6 (correct)

so ur solution is (-2,2)
