Answer 2

Solving the Equation |4x|=2.8

To solve the equation |4x| = 2.8, we need to consider two cases: when 4x is positive and when 4x is negative. We can then solve for x in each case.

1. When 4x is Positive: - In this case, the equation simplifies to 4x = 2.8. - Solving for x gives us x = 2.8 / 4. - Therefore, x = 0.7.

2. When 4x is Negative: - In this case, the equation simplifies to -4x = 2.8. - Solving for x gives us x = -2.8 / 4. - Therefore, x = -0.7.

So, the solutions for the equation |4x| = 2.8 are x = 0.7 and x = -0.7.

This is based on the properties of absolute value, where |a| = b implies that a = b or a = -b.
