Question

7. Find the value of the in the pair of simultaneous equations 3a -4b=10
and 5a -3b=24 *​

Answer 1

3a-4b=10

3a=10+4b

a=10+4b

3

putting the value of 'a' in the 2nd equation

24=5(10+4b) - 3b

3

24 =50+20b- (3) 3b

3

24×3 = 50 +20b -9b

72÷50 = 11b

b= 72

50×11

here you get the value of b. out this value in the first equation to find the value of a.
