Colton solved an equation incorrectly, as shown below:

step 1: x – 13 = 26

step 2: x = 26 – 13

step 3: x = 39

which statement best explains why step 2 is incorrect in colton's solution?

a he did not subtract 13 from 26.
b he did not multiply 26 by 13.
c he did not add 13 to 26.
d he did not divide 26 by 13.

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
