Answer:
6x + 4 = 40
Step-by-step explanation:
6 boxes
x = number of pencils per box
therefore Sam had 6x and received 4 more
Answer:
x = 5
Step-by-step explanation:
8x - 6x + 1 = 11
Add 6x to each side (because the 6 is negative)
8x + 1 = 11 - 6x
Subtract 1 from each side (because the 1 is positive)
8x = 10 - 6x
Subtract 6x from 8x
2x = 10
Divide by 2
x = 5
When a number is next to a letter like so: 3m You would multiply, so
3 ~ 2 = 6 then solve the problem like this
11-3m= ?
3~2=6
6-11=5
so 11-3m=5
Hope this helps! :)
