1. 10 and 2.160 and 3.28 and 32.
Step-by-step explanation:
We can also check our answer in both 1st and second part by putting the value in the equation...
for example in first part we got our ans 10 now we can check it
3x+10=40 this was our equation
now in place of x we will put 10.
(3×10)+10 =40
30+10=40
40 = 40
as forty equals to forty hence it is checked that our answer is correct. In the same way we can check the second part by puting 160 in place of X in the equation
4/5×X - 3/4×X = 8
...
28 and 32 are the two consecutive multiples of 4 whose sum is 60
