Answer:
m = -4.46
Step-by-step explanation:
-21.536 = -1.6(9 - m)
1.) Distribute.
-21.536 = -14.4 + 1.6m
2.) Add 14.4 to both sides.
-7.136 = 1.6m
3.) Divide both sides by 1.6.
-4.46 = m, or m = -4.46.
A+B = 2X -2
A-B = 4X -8
Add the equations,
2A = 6X - 10
A = 3X - 5
Now, 3X - 5 + B = 2X - 2
B = 2X-3X - 2 + 5
B = 3 - X
Hope this helps!
