Answer 1

Answer:

x = -2 and y = -2

Explanation:

Given equations:

3x - 2y = -2

5x - 3y = -4

---------------------

Make the value before y equal:

( 3x - 2y = -2 ) * 3

9x - 6y = -6 .........equation 1

( 5x - 3y = -4 ) * 2

10x - 6y = -8 ...........equation 2

solve them by elimination:

10x - 6y = -8

-9x + 6y = +6

----------------------

x = -2

If x is -2

Then y:

10x - 6y = -8 .................from equation 2

-6y = -8-10x

y = [-8 - 10(-2)]/-6

y = -2

Answer 2

• 3x-2y=-2--(1)
• 5x-3y=-4--(2)

• (1)×5 and (2)×3

$\\ \tt\hookrightarrow 15x-10y=-10--(3)$

$\\ \tt\hookrightarrow 15x-9y=-12--(4)$

Subtracting

$\\ \tt\hookrightarrow -y=+2$

$\\ \tt\hookrightarrow y=-2$

Put in eq(1)

$\\ \tt\hookrightarrow 3x+4=-2$

$\\ \tt\hookrightarrow x=-2$
