Answer :

Let's solve the equation step by step.

Given equation:
[tex]\[ \frac{0.2x + 1}{0.1} = 4 \][/tex]

Step 1: Eliminate the fraction by multiplying both sides of the equation by 0.1 to clear the denominator:
[tex]\[ (0.2x + 1) \times \frac{1}{0.1} \times 0.1 = 4 \times 0.1 \][/tex]
Simplifying both sides, we get:
[tex]\[ 0.2x + 1 = 0.4 \][/tex]

Step 2: Isolate the term with [tex]\(x\)[/tex]. Subtract 1 from both sides of the equation:
[tex]\[ 0.2x + 1 - 1 = 0.4 - 1 \][/tex]
Simplifying this, we get:
[tex]\[ 0.2x = -0.6 \][/tex]

Step 3: Solve for [tex]\(x\)[/tex] by dividing both sides of the equation by 0.2:
[tex]\[ x = \frac{-0.6}{0.2} \][/tex]

Upon simplifying the division, we find:
[tex]\[ x = -2.9999999999999996 \][/tex]

So the value of [tex]\(x\)[/tex] is approximately [tex]\(-3\)[/tex].
