Answer 3

To solve the equation 2.8 * (46 - 5x) = 29.4, follow these steps:

Step 1: Distribute the 2.8 on the left side of the equation.

2.8 * 46 - 2.8 * 5x = 29.4

Step 2: Simplify the equation.

128.8 - 14x = 29.4

Step 3: Move the constant term to the right side of the equation by subtracting 29.4 from both sides.

128.8 - 29.4 = 14x

99.4 = 14x

Step 4: Isolate x by dividing both sides by 14.

x = 99.4 / 14

x ≈ 7.1

So, the solution to the equation is x ≈ 7.1.
