Step-by-step explanation:
a 2m+5=13
2m=8
m=4
b 3m/5=-6
3m=-30
m=-10
c 4-5x=19
-5x=15
x=-3
d x/4-10=2
x=48
e -24=8(h+3)
-24=8h+24
-48=8h
h=-6
f -3+d/2=9
-3+d=18
d=21
Answer:
3ab+2cb,2ca+2ab+2bc
Step-by-step explanation:
1. Collect like terms.
3ab+2cb,((3ca-ca)+(-ab+3ab)+2bc)
3ab+2cb,((3ca−ca)+(−ab+3ab)+2bc)
2. Simplify (3ca-ca)+(-ab+3ab)+2bc(3ca−ca)+(−ab+3ab)+2bc to 2ca+2ab+2bc2ca+2ab+2bc.
3ab+2cb,2ca+2ab+2bc
3ab+2cb,2ca+2ab+2bc
