\huge \boxed{\mathbb{QUESTION} \downarrow}

  • Solve x+4/3x , if x = 2.

\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}

To solve this equation, at first, let's just substitute x with 2.

So, the equation becomes ⇨ 2+4/3×2

\tt \: \frac{x + 4}{3x}  \\  \\  \tt \:\dashrightarrow \frac{(2) + 4}{3(2)}  \\  \\ \tt \: Add \:  2  \: and  \: 4  \: to  \: get  \: 6. \\  \\ \tt \: = \frac{6}{3\times 2}  \\  \\ \tt \:Multiply  \: 3  \: and \:  2  \: to  \: get \:  6. \\  \\  \tt \:=  \frac{6}{6}  \\  \\\tt \: Divide \:  6 \:  by  \: 6 \:  to \:  get \:  1. \\  \\  = \boxed{ \boxed{ \bf \:  1}}

If you add​ Natalie's age and​ Fred's age, the result is 41. If you add​ Fred's age to 4 times​ Natalie's age, the result is 86.
max2010maxim [7]

Answer:

Fred = 26, Natalie = 15

Step-by-step explanation:

N + F= 41 // N = 41 - F (eqn 1)

4N + F = 86 (eqn 2)

sub eqn 1 into eqn 2

4(41 - F) + F = 86

164 - 4F + F = 86

-3F = - 78

F = 26

sub F = 26 into eqn 1

N = 41 - F

N = 41 - 26

N = 15
