Use a transformation to solve the equation.

Question

z – (–0.3) = –2.4

Question 2 options:

z = –2.7

z = 2.7

z = –2.1

z = 2.1

Answer 1

To solve the equation using a transformation, we can add 0.3 to both sides of the equation:

z - (-0.3) + 0.3 = -2.4 + 0.3

This simplifies to:

z = -2.1

Therefore, the solution is z = -2.1.
