Andre’s first mistake was that he didn’t distribute properly or at all. Instead of using the distributive property to get rid of the parenthesis, he moved the x to the 1/4 and subtracted 12 to the other side. Mistakes continue to occur from there so the equation solved would be:
1/4 (x+12)=2
1/4x+3=2
1/4x=-1
x=-4

His mistake is that he does not open the bracket first. The value of the x is negative of 4.

What is a BODMAS rule?

BODMAS rule means for the Bracket, Order, Division, Multiplication, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

Andre tried to solve the equation 1/4 ( x + 12 ) = 2.

First, open the bracket, then we have

[tex]\dfrac{x}{4} + \dfrac{12}{4} = 2[/tex]

On simplifying, we have

[tex]\dfrac{x}{4 } + 3 = 2[/tex]

Subtract 3 from both sides, we have

[tex]\dfrac{x}{4} = -1[/tex]

Multiply the equation by 4, we have

[tex]x = -4[/tex]
