Answer:
Q2) x=12
Q3) 66=29
Step-by-step explanation:
Q2) 7x−11=73
Step 1: Add 11 to both sides.
7x−11+11=73+11
7x=84
Step 2: Divide both sides by 7.
7x/7=84/7
x=12
Question 3:
Subtract 6 from 72
66 = 29
Answer: 11/12
Step-by-step explanation:
1. To solve this problem you can transform the mixed numbers given in the problem to fractions, as you can see below:
3 2/3=(3*3+2)/3=11/3
2 3/4=(4*2+3)/4=11/4
2. Now you must make the substraction of the fraction:
11/3-11/4=11/12
3. Therefore, the answer is 11/12
