Answer: x=-7/9, y=4/3. (-7/9, 4/3).

Step-by-step explanation: 6x+2y=-2

3x-2y=-5

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

9x=-7

x=-7/9

6(-7/9)+2y=-2

-42/9+2y=-2

2y=-2-(-42/9)

2y=-2+42/9

2y=-18/9+42/9

2y=24/9

y=(24/9)/2

y=(24/9)(1/2)

y=24/18

y=4/3

Answer:

Step-by-step explanation:

WR = 4 + 2 = 6

WS = 1/3 x WR = 2 .... the point of 1:2 of WR

S (-2 + 2 , -4) i.e. (0,4)

The same reason: RQ = 1/3 x RY = 1/3 x (5 + 4) = 3

<u>Answer:</u>

c= -1/2

<u>Step-by-step explanation:</u>

Let's solve your equation step-by-step.

4 /3 = −6c − 5/ 3

Step 1: Simplify both sides of the equation.

4 /3 =−6c + −5 /3

Step 2: Flip the equation.

−6c + −5 /3 = 4/3

Step 3: Add 5/3 to both sides.

−6c + −5 /3 + 5 /3 = 4/3 + 5 /3 −6c

=3

Step 4: Divide both sides by -6.

−6c −6 = 3 − 6 c = −1 /2
