Answer:
Step-by-step explanation:
13 = 6+7
276*13 = 276*(7+6)
= 276*7 + 276 *6 {distributive property upod addition}
= 1932 + 1656
= 3588
X/-3 = 12 + x
x = -36 - 3x
4x = 36
x= = 9
The number is 9.

Step-by-step explanation:
First your going to distribute the 3
3(-3x+15)
-9x+45
27=6x-9x+15

Then you’ll minus 15 from 27
27-15=12
12=3x
X=4
