Answer:
b) 3cd+3 1/3c-3d
Step-by-step explanation:
It can work well to factor the variables out so you can see the coefficients more easily:
6cd+3c-7d-3cd+4d+1/3c
= (6 -3)cd +(3 +1/3)c +(-7 +4)d
= 3cd +(3 1/3)c -3d
Answer: s= - 8/5
Step-by-step explanation:
Simplify 4-164−16 to -12−12.
-12=2+5(s+14)
−12=2+5(s+14)
2 Subtract 22 from both sides.
-12-2=5(s+14)
−12−2=5(s+14)
3 Simplify -12-2−12−2 to -14−14.
-14=5(s+14)
−14=5(s+14)
