Question

The linear equation 2a + 5b = - 2 has _______ solutions​

Answer 1

Answer:

infinte

Step-by-step explanation:

Answer 2

Step-by-step explanation:

2a+5b=13 ----- (1)

a+6b=10 ----- (2)

Substitute the values of first option a=4 and b=−1 in equations 1 and 2

2a+5b=13

2(4)+5(−1)=13

85=13

3



=13

a+6b=10

4+6(−1)=10

46=10

−2



=10

Therefore, the first option not satisfied the linear equations.

Likewise substitute the value of second option a=4,b=1

a+5b=13

2(4)+5(1)=13

8+5=13

13=13

a+6b=10

4+6(1)=10

4+6=10

10=10

Similarly, check the options to satisfy the linear equation.

Here, the second option satisfied the linear equation.

The solution is (4,1)
