Remove parentheses
-2x + 12 - 9 = 2 + 9 + 2x

Simplify -2x + 12 -9 to -2x + 3
-2x + 3 = 2 + 9 + 2x

Simplify 2 + 9 + 2x to 2x + 11
-2x + 3 = 2x + 11

Add 2x to both sides
3 = 2x + 11 + 2x

Simplify 2x + 11 +2x to 4x + 11
3 = 4x + 11

Subtract 11 from both sides
3 - 11 = 4x

Simplify 3 - 11 to - 8
-8 = 4x

Divide both sides by 4
-8/4 = x

Simplify 8/4 to 2
-2 = x

Switch sides
x = -2

H₀ : μ = $2,100

H₀ : μ < $2,100

The probability that the null hypothesis is rejected when the average gain is $2,100 is 0.01

specify the rejection region of a large sample test

At the given level of significance 0.01 and the test is left-tailed then rejection level of a large-sample = < - 1.28
