Answer:
Carl is incorrect, he didn't write an equivalent expression and he didn't use the distributive property in the equation.
Step-by-step explanation:
When solving equations, we use PEMDAS
P = Parenthesis
E = Exponent
M = Multiply
D = Divide
A = Add
S = Subtract
So lets solve the equation then:
6 - 4 (3 - 6x) + 12x
Use the distributive property to multiply −4 by 3 and -6x
6 - 12 + 24x + 12x
Subtract 12 from 6 to get −6
-6 + 24x + 12x
Combine 24x and 12x to get 36x
-6 + 36x
So, -6 + 36x is the answer
And the reason why Felipa is correct, is because Felip wrote an equivalent expression, she correctly multiplied -4 (3 - 6x) before adding or subtracting and she combined like terms correctly.
The reason why Carl is incorrect, is because he didn't write an equivalent expression and he didn't use the distributive property in the equation.
