100 POINTS solve the system using linear combination. show all work.{ 5x + 3y = 41 {3x - 6y = 9

PIT_PIT [208]

Answer:

y = 2

x = 7

Explanation:

5x + 3y = 41

3x - 6y = 9

Make the coefficient of "y" in equation 1 same

{ 5x + 3y = 41 } * 2 → 10x + 6y = 82 ........equation 1

→ 3x - 6y = 9 ........equation 2

solving them using linear combination

10x + 6y = 82

3x - 6y = 9

============

13x = 91

x = 7

Find y:

5x + 3y = 41

5(7) + 3y = 41

3y = 41 - 35

3y = 6

y = 2

Add $\frac{x}{2}$ to both sides:

$\dfrac{2x}{5}+\frac{x}{2} = 9$

Add the fractions in the left hand side:

$\dfrac{2x}{5}+\frac{x}{2} = \dfrac{4x}{10}+\frac{5x}{10}=\dfrac{9x}{10}$

So, the equation becomes

$\dfrac{9x}{10}= 9$

Multiply both sides by 10:

$9x = 90$

Divide both sides by 9:

$x = 10$
