Question

Solve the given system of equations. The solution to the system is ( , ).

Answer 1

Answer:

x=3

y=1

Step-by-step explanation:

First, get x and y on the left in the lower equation. -2x+10y=4. Then solve using a calculator. Select (apps), PlySmlt2, Simultaneous EQN Solver, and enter your euqations in.

Answer 2

Answer:

(3, 1)

Step-by-step explanation:

I will show the strategy of elimination in my solution, you can use other strategies but I will use elimination.

Line up variables:

4x - 3y = 9

10y = 2x + 4 -> -2x + 10y = 4

Multiply by 2 for elimination:

-4x + 20y = 8

Now we can add the equations together:

17y = 17

y = 1

Since we know that y is 1, we can plug that into an equation in the system and see what x is.

4x - 3 = 9

4x = 12

x = 3

x = 3

y = 1

Check our answer:

12 - 3 = 9 - Correct

10 = 6 + 4 - Correct
