-4xy^6 * -3x = 12x^2y^6
-4xy^6 * 2y = -8xy^7
6 * -3x = -18x
6 * 2y = 12y
Answer = 12x^2y^6 + -8xy^7 + -18x + 12y

5(m+2)-m=2m+3<br><br>Please I need help

Blababa [14]

Answer:

m=-7/2

Step-by-step explanation:

(5 • (m + 2) - m) - (2m + 3) = 0

2m + 7 = 0

3.1 Solve : 2m+7 = 0

Subtract 7 from both sides of the equation :

2m = -7

Divide both sides of the equation by 2:

m = -7/2 = -3.500

17x-3y=4 2x-4y=1 the solution to the system of equations is

Burka [1]

ANSWER

$x=\frac{13}{62}$

and

$y= \frac{-9}{62}$ e have

EXPLANATION

$17x-3y=4---(1)$

$2x-4y=1$

Let us make y the subject and call it equation (2)

$2x=1+4y$

$x=\frac{1}{2}+2y--(2)$

We put equation (2) in to equation (1)

$17(\frac{1}{2}+2y)-3y=4$

$\frac{17}{2}+34y-3y=4$

$34y-3y=4- \frac{17}{2}$

Simplify to get,

$31y= \frac{8-17}{2}$

$31y= \frac{-9}{2}$

Divide both sides by 31,

$y= \frac{-9}{2} \div 31$

$y= \frac{-9}{2} \times \frac{1}{31}$

$y= \frac{-9}{62}$

We put this value in to equation (2) to get,

$x=\frac{1}{2}+2\times -\frac{9}{62}$

$x=\frac{1}{2} -\frac{18}{62}$

We collect LCM to obtain,

$x=\frac{31-18}{62}$

$x=\frac{13}{62}$
