Brianna solved a two-step equation, but she made a mistake along the way. 0.1x + 3 = 1.7 (-3) + 0.1x + 3 = 1.7 + (-3) line 1 0.1x = -1.3 line 2 (-0.1) + 0.1x = -1.3 + (-0.1) line 3 x = -1.4 line 4 what mistake did brianna make? on line 1, brianna should have subtracted 3 instead of adding -3. on line 1, brianna violated the addition property of equality. on line 3, brianna should have divided by 0.1 instead of subtracting 0.1. on line 3, brianna violated the addition property of equality.

The appropriate choice is ...

... On Line 3, Brianna should have divided by 0.1 instead of subtracting 0.1.

Had Brianna simplified her effort properly on line 4, she would have

... -0.1 +0.1x = -1.4

putting her essentially back where she started—with a 2-step equation.
