If (a,-5) is a solution to the equations 3a=-2b-7, what is a?

a = 1

Step-by-step explanation:

Given : If (a,-5) is a solution to the equations 3a=-2b-7,

To find : what is a

Solution : We have given

(a,-5) is a solution to the equations 3a=-2b-7,

For a = a and b = -5.

3a = - 2(-5) - 7.

3a = 10 -7 .

3a =  3.

On dividing both side by 3.

a = 1

Therefore, a = 1

a

step-by-step explanation:

the answer is a
