To solve this equation for x, we'll follow the steps below:
Given equation:
2.8 / (0.3 - x) = 7
Step 1: Multiply both sides of the equation by (0.3 - x) to eliminate the fraction.
(0.3 - x) * (2.8 / (0.3 - x)) = 7 * (0.3 - x)
The (0.3 - x) term in the numerator and denominator of the left-hand side of the equation will cancel out, leaving us with:
2.8 = 7 * (0.3 - x)
Step 2: Distribute 7 on the right-hand side of the equation.
2.8 = 2.1 - 7x
Step 3: Move like terms to the same side of the equation.
2.8 - 2.1 = -7x
0.7 = -7x
Step 4: Divide both sides by -7 to isolate x.
0.7 / -7 = x
x = -0.1
So, the solution to the equation is x = -0.1.
