Question

4 30
3a + 5b = 26; a + 5b = 22
Solve the following simultaneous equatior​

Answer 1

Answer:

a=2, b=4

Step-by-step explanation:

Using subtitution method

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

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

- - -

2a=4

a=4/2

a=2

Substitute a in equation(ii)

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

2+5b=22

5b=22-2

5b=20

b=20/5

b=4

Answer 2

Question:

Solve the Following Simultaneous Equation.

3a + 5b = 26;

a + 5b = 22

Step-by-step explanation:

3a + 5b = 26    ___(l)

a + 5b = 22    ___(ll)

Subtracting (ll) from (l)

2a = 4

a = 2

Putting the value of a = 2 in (ll)

a + 5b = 22

⇒ 2 + 5b = 22

⇒ 5b = 20

⇒ b = 4
