Alice wanted to solve for x by getting rid if the +8. explain and correct Alice error

ra1l [238]

Answer: The value of x will be 2.

Step-by-step explanation:

To calculate the value of 'x' or solve for x, we need to isolate x from 8.

In the equation, 8 is in addition with 'x' so for isolating it, we need to apply the reverse operation of addition.

Reverse operation of addition is subtraction.

We need to subtract 8 from both sides of the equation, we get:

$x+8-8=10-8\\\\x=2$

By doing this, we get the value of 'x' as 2.

Error done by Alice was that she added 8 and it did not led to the isolation of 'x'.

Anyone here who can help me with this?

Mandarinka [93]

Answer:

D. 16 years old

Step-by-step explanation:

Step 1: Let T be Tien's age and J as Jordan's age (today),

$T=\frac{1}{4}J$

Step 2: Let T be Tien's age and J as Jordan's age (in 2 years),

$T+2=\frac{1}{3} (J+2)$

$T=\frac{1}{3}(J+2)-2$

Step 3: As their age differences will always be similar we can have the two equations above equal to find Jordan's age,

$\frac{1}{4} J=\frac{1}{3}(J+2)-2\\\frac{1}{4}J-\frac{1}{3}J=\frac{2}{3} -2 \\-\frac{1}{12}J= -\frac{4}{3} \\\\J=16$
