Question

1. Solve the equation x+8=21+5x. 2. Solve the equation a. 1/m=4/5 b. 4/x=8. 3. Solve the equation 5p-4/3=p+2 4. Solve the equation 2y-2/2 +2y+2/3=3. Wrong answer will be reported.

Answer 1

Answer:

x+8=21+5x

Trying to factor as a Difference of Squares

Theory : A difference of two perfect squares,  A2 - B2  can be factored into  (A+B) • (A-B)

Proof :  (A+B) • (A-B) =

        A2 - AB + BA - B2 =

        A2 - AB + AB - B2 =

        A2 - B2

Note :  AB = BA is the commutative property of multiplication.

Note :  - AB + AB equals zero and is therefore eliminated from the expression.
