Angela tried to solve an equation step by step. \begin{aligned} \dfrac34+m&=\dfrac54 \dfrac34+m-\dfrac34&=\dfrac54+\ dfrac34&\green{\text{Step } 1} m&=2&\blue{\text{Step } 2} \end{aligned} 4 3 +m 4 3 +m− 4 3 m = 4 5 = 4 5 + 4 3 =2 Step 1 Step 2 Find Angela's mistake.

The mistake she made was ; She didn't change the sign when subtracting -3/4 from both sides

She wrote 5/4+3/4 instead of 5/4-3/4

Step-by-step explanation:

Correct solution:

Subtract-3/4 from both sides

Simplify

The mistake she made was in step 1

Step-by-step explanation:

its on khan academy.

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

the answer will be b x² +x-1
