Answer:
20.
m = -52
22.
x=13
24.
a=-90
26.
n=-2
28.
a=9
30.
m=-10
Step-by-step explanation:
20. m/4=-13
m = -13*4 = -52
22. -143=-11x
x=-143/-11 =13
24. -5=a/18
a=-5*18= -90
26. n-8=-10
n=--10+8
28. a+11=20
a=20-11
30. 18+m=8
m=8-18
p = 1.2
Bring 3.9 to the other side of the equation.
-10.9p = -13.08
