Answer:
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
