Solve 3x – ly= 11 and -2x – 4y=-26 by elimination

Ede4ka [16]

Answer:

(5, 4 )

Step-by-step explanation:

Given the 2 equations

3x - y = 11 → (1)

- 2x - 4y = - 26 → (2)

Multiplying (1) by - 4 and adding to (2) will eliminate the y- term

- 12x + 4y = - 44 → (3)

Add (2) and (3) term by term to eliminate y

- 14x + 0 = - 70

- 14x = - 70 ( divide both sides by - 14 )

x = 5

Substitute x = 5 into either of the 2 equations and solve for y

Substituting into (1)

3(5) - y = 11

15 - y = 11 ( subtract 15 from both sides )

- y = - 4 ( multiply both sides by - 1 )

y = 4

solution is (5, 4 )

Determine if the given order pair si a solution to the equation. Show work...

lozanna [386]

The given ordered pair is not the solution to the equation

Step-by-step explanation:

In order to find if an ordered pair is a solution to the equation or not, we plug in the values of x and y in the equation. If the equation is true for the point then the ordered pair is the solution to the equation.

Given equation is:

$y = -3x-13$

Putting x=-1, y=15

$15 = -3(-1)-13\\15 = 3-13\\15 \neq -10$

The given ordered pair is not the solution to the equation
