Question

4a+b=34 and a+4b=16 find the value of a and b
pls help​

Answer 1

Answer:

As 4a+b=34

b=34-4a

Putting values in second equation

a+4(34-4a)=16

a+136-16a=16

-15a=16-136

15a=136-16

15a=120

a=120/15

a=8

Putting Value of a in first equation to get b

4(8)+b=34

32+b=34

b=34-32

b=2

So, a=8 and b=2
