Question

3a_4b=1, 4a+3b=2 the a and b value

Answer 1

Answer:3a-4b=1........1

4a+3b=2...........2

now equation 1 by multiply 3 and equation 2 by multiply 4

9a-12b=3

16a+12b=8

__________

25a=11

a=11/25

Now equation 1

3a-4b=1

3(11/25)-4b=1

3(11)-25(4b)=25

33-100b=25

-100b=25-33

-100b=-8

100b=8

b=8/100

b= 2/25

So a=11/25 and b=2/25
