Question

Need an answer for both plez.

Answer 1

(2, 13)

Explanation:

Since they both equal y, you can equal them to each other.

8x - 3 = 2x + 9

Subtract 2x from both sides.

6x - 3 = 9

Add 3 to both sides.

6x = 12

Now divide 6 on both sides.

x = 2

Now that we have found x, we need to find y. Just plug in x to the equations.

y = 2(2) + 9

y = 4 + 9

y = 13

Now, if the next equal has the same y, then both are true.

8(2) -3 = y

16-3=y

13 = y

So therefor, both x and y are true.
