True or false: the given number is a solution to the corresponding equation

a=−3

4a+3=−9

TRUE.

a = -3 is a Solution to the equation 4a + 3 = -9  

Step-by-step explanation:

Given:

a = -3

4a + 3 = -9

Proof for Solution:

Let there be two part of the equation, left-hand side and right hand side.

If a  = -3 is a solution ,

left-hand side = right hand side

left-hand side = 4a +3

                       = 4×-3 + 3{ For a = -3}

                       = -12 + 3

                       = -9

                       = right hand side

∴ left-hand side = right hand side

∴ a = -3 is a Solution to the equation 4a + 3 = -9
