Question

Solve the equation. Simplify your answer if possible.

-2.1 = 2.5z - 2.6
The solution set is { }

Answer 1

-2.1 = 2.5z - 2.6

-2.5z = -2.6 + 2.1

-2.5z = -0.5

z = -0.5 ÷ (-2.5)

z = 0.2

Answer 2

Explanation:

-2.1 = 2.5z - 2.6

-2.1 + 2.6 = 2.5z

0.5 = 2.5z

0.5/2.5 = z

5/25 = z

1/5 = z

0.2 = z

Set {0.2}
