3(4x +12)=180
12x + 36 =180
-36. -36
180-36= 144
12x = 144

12. 12
X = 12
Answer:
n = 64
Step-by-step explanation:
We can solve using cross products
10/15 = n/96
10*96 = 15*n
960 = 15n
Divide each side by 15
960/15 =15n/15
64 = n
So 4 6/8= (32/4)+6/8=38/8
11 1/3=(33/3)+1/3=34/3
so 38/8+(34/3)
to add you must get the bottom number equall so
114/24+272/24=386/24=16 1/12
