Answer 2

Answer:

$\Huge\boxed{\mathsf{X=-\frac{240}{29}=-8.27 }}$

Step-by-step explanation:

To solve this problem, first, you have to isolate it on one side of the equation. Remember to solve this problem, isolate x on one side of the equation.

21.4x +149=4x+5

21.4x*10+149*10=4x*10+5*10 (First, multiply 10 from both sides.)

5*10 (Solve.)

5*10=50

Rewrite the problem down.

214x+1490=40x+50

214x+1490-1490=40x+50-1490 (Next, subtract by 1490 from both sides.)

1490-50 (Solve.)

1490-50=1440

214x=40x-1440

214x-40x=40x-1440-40x (Subtract by 40x from both sides.)

214x-40x (Solve.)

214x-40x=174x

174x=-1440

174x/174=-1440/174 (Then, divide by 174 from both sides.)

-1440/174 (Solve.)

-1440/174=-240/29

-240/29=-8.27

x=-240/29=-8.27

$\bigstar \Rightarrow \Large\boxed{\mathsf{X=-\frac{240}{29}=-8.27 }}\bigstar$

In conclusion, the correct answer is x=-240/29=-8.27.
