21x =7? A. x=3 B. None of these C. x=147 D. x=28

Varvara68 [4.7K]

Answer: B

Step-by-step explanation:

To isolate x, you divide both sides by 21

21x=7

$\frac{21x}{21}=\frac{7}{21}$

x = 7/21

Simplify by dividing both the numerator and denominator by 7

x = 1/3

Since, 1/3 is not an option, B is the correct answer

Andre tried to solve the equation 1/4(x + 12) = 2. What was his mistake? *

Umnica [9.8K]

Answer:

x=-4

Step-by-step explanation:

x+12=8

x=8-12

Andre did not multiple both by four to get the exact whole number. He also, didnt subtract 12 which is not possible due to it being multiplied by 1/4.
