Answer:
x= -6.2
Step-by-step exp
2+4(x-5) =9x+13
2+4x-20 =9x+13
2+4x =9x+13+20
2 =9x+33-4x
2 = 9x-4x+33
2 = 5x+33
2-33 = 5x
-31 = 5x
-31/5 = x
-6.2 = x
Proof
Replacing x in the equation with its value
2+4(x-5) =9x+13
2+4(-6.2-5) = 9* (-6.2) + 13
2+4(-11.2) = -55.8+13
2-44.8 = -42.8
-42.8 = -42.8
As the equation is true when x = -6.2
Therefore, x = -6.2 proved
