Answer: the most straight-forward way to prove this is to plug -5 in the equation as the value of x. If the the equality holds, it is proven that x=-5:
3x+1=-14 | use x=-5
3(-5)+1=-14
-15+1=-14
-14=-14 --> equality holds --> x=-5 is a solution to 3x+1=-14
Answer:
Given,
[tex]3x+1=-14----(1)[/tex]
We have to prove that,
x = - 5
Subtracting 1 on both sides in equation (1), ( Subtraction property of equality )
[tex]3x+1-1=-14-1[/tex]
[tex]3x=-15[/tex]
Divide both sides by 3 ( division property of equality )
[tex]x=\frac{-15}{3}[/tex]
[tex]x=-5[/tex]
Hence, proved....
