Answer:

1. 3

2. 2

3. 2

4. 6

5. No solution

Step-by-step explanation:

2x+3y=8 (1)

-6x+4y=11 (2)

3(1) + (2)

6x + 9y = 24

-6x + 4y = 11

13y = 35

y = 35/13

x = -1/26

3x-y=3 (1)

-2x+2y=6 (2)

2(1) + (2)

6x - 2y = 6

-2x + 2y = 6

4x = 12

x = 3

y = 3(3) - 3 = 6

3x+4y=-10 (1)

5x-2y=18 (2)

(1) + 2(2)

3x + 4y = -10

10x - 4y = 36

13x = 26

x = 2

5x-2y=3 (1)

2x-y=0 (2)

(1) - 2(2)

5x - 2y = 3

-4x + 2y = 0

x = 3

2(3) - y = 0

y = 6

3x+2y=10 (1)

6x+4y=14 (2)

2(1) - (2)

6x + 4y = 20

6x + 4y = 14

0 = 6 is a false statement so no solution

Solve for x and y: <br> Thanks for the help!
sweet-ann [11.9K]

Answer:

x = 2

y = 15

Step-by-step explanation:

As the triangle is split with a line that is parallel to the base:

\implies x:6=6:18

\implies \dfrac{x}{6}=\dfrac{6}{18}

\implies x=\dfrac{6\cdot 6}{18}

\implies x=\dfrac{36}{18}

\implies x=2

Similarly:

\implies y:20=6 : (6+x)

\implies y:20=6:8

\implies \dfrac{y}{20}=\dfrac68

\implies y=\dfrac{6 \cdot 20}{8}

\implies y=\dfrac{120}{8}

\implies y=15
