6. Solve the the following system of equations: 4y+2x=14 2y+2x=10
Inessa05 [86]
4y+2x=14 ==> multiply this 1st equation by (-1) => -4y-2x=-14
Now add it up to the 2nd equation
-4y-2x=-14
 2y+2x=10
--------------    And now add them up
-2y +0x=-4
==> -2y=-4==> 2y = 4 &    y=2                   
Last step: plug y into any equation & you will find x=3

Write down the solution to the simultaneous equations.
julia-pushkina [17]

Answer:

x = 5/2; y = 7

Step-by-step explanation:

2x + y = 12

y = 2x + 2

Use substitution to replace y in the first equation with 2x + 2.

2x + 2x + 2 = 12

4x + 2 = 12

4x = 10

x = 10/4

x = 5/2

y = 2x + 2

y = 2(5/2) + 2 = 5 + 2

y = 7
