5ab-2ab+4a-b+5b = 3ab+4a+4b

Add the equations: 4a + 4a - 5b + 5b = 7 + 17 ie 8a = 24 a = 3, so b = 1

The expression is: (4a+b)/(2a-5b)

3a - 2b

2a+6b

(1) 4a-5b=7 (2) 4a+5b=17 (1)-(2) gives 4a-5b-(4a+5b)=7-17 then -10b=-10 so b=1 from (2) one gets 4a=17-5b=17-5x1=12 so a=3 (3,1) is the solution

4a - 5b = 74a +5b = 17From the first equation:4a = 7 + 5bsubstitute this value in the second equation:7 + 5b + 5b = 177 + 10b = 1710b = 10b = 1Now,solve for a :4a - 5(1) = 74a = 7 + 54a = 12a = 3

5ab-2ab+4a-b+5b = 3ab+4a+4b

Add the equations: 4a + 4a - 5b + 5b = 7 + 17 ie 8a = 24 a = 3, so b = 1

The expression is: (4a+b)/(2a-5b)

3a - 2b

4(a+5b)

8b -2a

No. 7b - 2b = 5b

3a - 2b

2a+6b
