I am so sorry I would love to help you but I haven't gotten that far in my classes, how long do you have? My sister should be coming home soon and she's learned this before
Answer:
Distributive property of multiplication
Step-by-step explanation:
(6+3)*4 = 6*4 + 3*4
9*4 =36 24+12 = 36
6x+3=45
6x+3-3=45-3
6x= 42
Divide by 6 for 6x and 42
6x/6= 42/6
x= 7
Check answer by using substitution method
6x+3= 45
6(7)+3= 45
42+3= 45
45= 45
The answer is x= 7
24 because
6x4=24
8x3=24
since that makes the two denominador alike than they are common (alike) and they are the denominators (duh)
