Answer 2

To solve the equation for x, let's follow the order of operations (PEMDAS/BODMAS) and simplify the expression step by step:

Given equation: -3 + 1 / 4 * x = -3.5

Step 1: Distribute the multiplication (since it has a higher priority than addition/subtraction): -3 + (1/4) * x = -3.5

Step 2: Move the constant term to the other side of the equation: (1/4) * x = -3.5 + 3

Step 3: Simplify the constant term on the right side: (1/4) * x = -0.5

Step 4: To isolate x, divide both sides by (1/4): x = -0.5 / (1/4)

Step 5: To divide by a fraction, multiply by its reciprocal: x = -0.5 * (4/1)

Step 6: Simplify the expression: x = -0.5 * 4

Step 7: Perform the multiplication: x = -2

So, the value of x that satisfies the equation is x = -2.
