Help ! solve the following system of equations -9x+2y=-13 2x-9y=20

Stella [2.4K]

Answer: x = 1, y = -2

Step-by-step explanation:

-9x+2y=-13

x= 13/9 + 2/9y

2x-9y=20

2(13/9+2/9y)-9y=20

Substitute y with -2.

x= 13/9+2/9(-2)

After solving you'll see that 1 is a possible solution for x.

Check your answer

-9x+2y=-13

-9x1+2(-2) = -13

2x-9y=20

2x1-9(-2) = 20

-13 = -13

20 = 20

Therefore, x=1 and y=-2

M is between L and N. If LN = 91 and LM = 23, find MN.

Tasya [4]

Answer:

MN = 68

Step-by-step explanation:

LN = 91

LM = 23

Points L, M, and N are collinear, therefore, according to the segment addition postulate, the following can be deduced:

LM + MN = LN

23 + MN = 91 (Substitution)

Subtract 23 from both sides

23 + MN - 23 = 91 - 23

MN = 68

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

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.
