Answer 3

To solve the equations, let's start by simplifying them step by step:

Equation 1: x - 0.7 = 2.2x / 0.01

Multiply both sides of the equation by 0.01 to get rid of the fraction:

0.01(x - 0.7) = 2.2x

0.01x - 0.007 = 2.2x

Next, let's isolate the x term on one side by subtracting 0.01x from both sides:

0.01x - 0.01x - 0.007 = 2.2x - 0.01x

-0.007 = 2.19x

Now, divide both sides by 2.19 to solve for x:

-0.007 / 2.19 = x

x ≈ -0.0032

So the solution for Equation 1 is x ≈ -0.0032.

Now let's move on to Equation 2: 0.01 = 2.2 + 3(x - 5.1) / 0.2

Multiply both sides by 0.2 to eliminate the fraction:

0.2 * 0.01 = 0.2 * (2.2 + 3(x - 5.1)) / 0.2

0.002 = 0.44 + 3(x - 5.1)

Subtract 0.44 from both sides:

0.002 - 0.44 = 0.44 + 3(x - 5.1) - 0.44

-0.438 = 3(x - 5.1)

Divide both sides by 3:

-0.438 / 3 = (x - 5.1)

-0.146 = x - 5.1

Add 5.1 to both sides:

-0.146 + 5.1 = x - 5.1 + 5.1

4.954 = x

So the solution for Equation 2 is x = 4.954.

Therefore, the solutions to the given equations are: Equation 1: x ≈ -0.0032 Equation 2: x = 4.954
