Question

3a+5b=26;a+5b=22solve in simulation equation for 10th standard​

Answer 1

Answer:

3a+5b=26----------(i)

a+5b=22-----------(ii)

By estimation method

3 a + 5b = 26

a + 5b = 22

(-) (-) (-)

________________

2a = 4

a = 2 --------------(iii)

putying (iii) in (i)

3 (2) + 5b = 26

5b = 26 -6

b = 20/5

b = 4.
