Answer:
what is the 2nd problem????
Step-by-step explanation:
Answer:
n = -7
Check:
-4 - 3 + 5 + 4 - 3 + (-7 ÷ -7) = 0
-1 - 7 ÷ -7 = 0
-1 + 1 = 0
0 = 0
Answer: The number is 23
Step-by-step explanation:
Let x be the [number]
Rephrase the expression
a number increased by 11 is equal to twice the number decrease by 12
x+11=2x-12
Add 12 on both sides
x+11+12=2x-12+12
x+23=2x
Subtract x on both sides
x+23-x=2x-x
x=23
Hope this helps!! :)
