Solve x + 3y = 9<br> 3x – 3y = -13 (1 point)

Mariana [72]

Answer:

The values of x and y to the given equations are x=-1 and $y=\frac{10}{3}$

The solution is (-1, $\frac{10}{3}$ )

Step-by-step explanation:

Given equations are $x+3y=9\hfill (1)$

and $3x-3y=-13\hfill (2)$

to solve the given equations by elimination method :

Adding the given two equations (1) and (2) we get

$x+3y=9$

$3x-3y=-13$

_______________

4x=-4

$x=-\frac{4}{4}$

Therefore x=-1

Now substitute the value x=-1 in equation(1) we get

(-1)+3y=9

3y=9+1

$y=\frac{10}{3}$

Therefore the values of x and y to the given equations are x=-1 and $y=\frac{10}{3}$

The solution is (-1, $\frac{10}{3}$ )

Which point represents the solution to the system

Alborosie

Answer:

Step-by-step explanation:

$3x - 2y = 12 \\ 2x + 2y = 3 \\ 2y = 3 - 2x \\ 3x - (3 - 2x) = 12 \\ 3x - 3 + 2x = 12 \\ 5x = 15 \\ x = 3 \\ 2y = 3 - 6 = - 3 \\ y = - \frac{3}{2}$

(3, -3/2)
