Answer:
5k and -3k are like variables
constants 7 and -2 are like terms
5+2k+n is equivalent expression
Step-by-step explanation:
What are the numbers x and y are sopposed to be?
W=2j, m=5w, (m+4)=6(j+4)
using w from first in second you get:
m=5(2j)=10j, m+4=6j+24
m=10j, m=6j+20, since m=m we can say
10j=6j+20
4j=20
j=5, and since m=10j
m=50
So the man is 50 years old
Okay Let's say
2x + 3 = 45
-3 -3
----------------
2x = 42
--- ---
2 2 x = 21
