Answer 2

To solve the equation |x + 1.5| + 2.2 = 4.7, we'll start by isolating the absolute value term and then solve for x.

Subtract 2.2 from both sides of the equation: |x + 1.5| = 4.7 - 2.2 |x + 1.5| = 2.5

Now, we'll split the equation into two cases: positive and negative values for the absolute value.

Case 1: x + 1.5 ≥ 0 (positive) In this case, the absolute value term remains as is. x + 1.5 = 2.5

Solving for x: x = 2.5 - 1.5 x = 1

Case 2: x + 1.5 < 0 (negative) In this case, the absolute value term becomes its negation. -(x + 1.5) = 2.5

Solving for x: -x - 1.5 = 2.5 -x = 2.5 + 1.5 -x = 4

To get the final answer, we need to consider the absolute value's negative solution, which means x = -4.

Therefore, the solutions to the equation |x + 1.5| + 2.2 = 4.7 are x = 1 and x = -4.
