So you’re trying to get the a on it’s own while you use +-x/ operations.
For this one you divide both sides by 2 to get the a alone.
2a/2=12/2
a=6
N- a number
The sum of 18 and a number: 18 + n
Answer:
60m - 36
Step-by-step explanation:
<em>This equation is asking you what is this quantity times 12? So you distribute the 12 (multiply everything in the quantity by 12)/</em>
(5m - 3)12
12 x 5m = 60m
12 x (-3) = -36
60m - 36
Answer:
Figure out what x is for both equations, then you can tell if the equations are the same
Step-by-step explanation:
1. 4x+1=9
x = 2
4 x 2= 8
2x+1=5
x = 2
2 x 2 = 4
4 does not = 9 so no.
