Final answer:
To solve the equation -3.5 + x/0.4 = -2 for x, isolate x by adding 3.5 to both sides and then multiplying by 0.4.
Step-by-step explanation:
To solve the equation -3.5 + x/0.4 = -2 for x, we can start by isolating x. To do this, we can begin by adding 3.5 to both sides of the equation:
-3.5 + x/0.4 + 3.5 = -2 + 3.5
Simplifying the equation, we'll have:
x/0.4 = 1.5
To eliminate the fraction, we can multiply both sides of the equation by 0.4:
x/0.4 * 0.4 = 1.5 * 0.4
This simplifies to:
x = 0.6
