Question

solve the following simultaneous equations
3a+5b=26;a+5b=22
​

Answer 1

Answer:

Step-by-step explanation:

Solve the following simultaneous equation.

3a+5b=26;a+5b=22

Solution

3a+5b=26              

a+5b=22            

Subtracting (II) from (I)

2a=4

⇒a=2

Putting the value of a=2 in (II)

5b=22−2=20

⇒b=  

5

20

​

=4

Thus,a=2 and 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
