Question

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

Answer 1

Answer:

a=2

b=4

Step-by-step explanation:

On subtracting equation 2 from equation 1

3a+5b = 26

a +5b= 22

2a = 4

a = 2

Now put a=2 in eq2

a+5b = 22

2+5b = 22

5b = 22-2

b = 20/5

b = 4

Answer 2

answer:

a=2

b=4

step by step explaination:

3a+5b=26. _________(1)

a+5b=22. _________(2)

subtracting (1) and (2);

3a+5b=26

( -)a+5b=22

______________

2a=4

a=2. __________(3)

putting (3)in(2);

a+5b=22

2+5b=22

b=22-2/5

b=4}

a=2}ans
