X+2y=8 under it is x-3y =6 solve it using simultaneous equation,substitution method.

cupoosta [38]

Answer:

Step-by-step explanation:

x +2y = 8 ----- (I)

x = 8 - 2y

x - 3y = 6 -------(II)

Substitute x = 8 - 2y in equation (II)

8 - 2y - 3y = 6 {add like terms}

8 - 5y = 6

Subtract 8 form both sides

-5y = 6- 8

-5y = -2

Divide both sides by -5

-5y/-5 = -2/-5

y = 2/5

Substitute y = 2/5 in equation (I)

$x+2*\frac{2}{5}=8\\\\x+\frac{4}{5}=8\\\\x=8- \frac{4}{5}\\\\x=\frac{8*5}{1*5}-\frac{4}{5}\\\\x=\frac{40}{5}-\frac{4}{5}\\\\x=\frac{36}{5}$

x = 36/5

Plz solve this question

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

Simplify ⇨ 1/x(x+a) + 1/x(x-a)

$\large \boxed{\mathbb{ANSWER \: WITH \: EXPLANATION} \downarrow}$

$\sf\frac { 1 } { x ( x + a ) } + \frac { 1 } { x ( x - a ) } \\$

To add or subtract expressions, expand them to make their denominators the same. Least common multiple of $x\left(x+a\right)$ and $x\left(x-a\right)$ is $x\left(x+a\right)\left(x-a\right)$ . Multiply $\frac{1}{x\left(x+a\right)} times \frac{x-a}{x-a}$ . Multiply $\frac{1}{x\left(x-a\right)} times \frac{x+a}{x+a}$ .

$\sf\frac{x-a}{x\left(x+a\right)\left(x-a\right)}+\frac{x+a}{x\left(x+a\right)\left(x-a\right)} \\$

Because $\frac{x-a}{x\left(x+a\right)\left(x-a\right)}$ and $\frac{x+a}{x\left(x+a\right)\left(x-a\right)}$ have the same denominator, add them by adding their numerators.
