Solve this linear system by graphing x-y=6 2x=12+2y

1 answer:

5 0

You need to isolate the variables. For the first equation add x to both sides, which leaves you with y.

For the second equation, divide each side by 2 leaving you with
x= 6+y. Subtract y from each side. Subtract x from both sides. Now you have y= x + 6.

Now graph those equations.

Separate the x- and y-values with a comma. X=-3+y 26x - 5y = 6

Answer:

The solution of the given system is (x,y) = (1,4)

Step-by-step explanation:

Here, the given system of equation is:

x = -3 + y

26 x - 5 y = 6

Now, substitute x = -3 + y in the second equation , we get

26 x - 5 y = 6 ⇒ 26 (-3 + y) - 5 y = 6

or, 26(-3) + 26(y) - 5y = 6

⇒ - 78 + 26 y - 5y = 6

⇒ 21 y = 84

⇒ y = 84 / 21 = 4 or , y = 4

So x = -3 + y = -3 + 4 = 1

Hence, the solution of the given system is (x,y) = (1,4)
