The ordered pairs for the intercepts are as follows:

x intercept = 9/2

y intercept = -18

In order to find either of these you must put 0's in for the other variable. So, to find the x intercept, we start by putting 0 in for y.

y = 4x - 18

0 = 4x - 18

-4x = -18

x = 9/2

To find the y intercept, we put a 0 in for x.

y = 4x - 18

y = 4(0) - 18

y = 0 - 18

y = -18

Solve the simultaneous equation:<br> 5 x + 2 y = 25 <br> 5 x − y = 10

Liono4ka [1.6K]

Answer:

(x, y) = (3, 5)

Step-by-step explanation:

$5x+2y=25\\5x-y=10$

Solving by elimination here again, there are 2 good options available. Either multiply the whole bottom equation by -1 to cancel the x, or by 2 to cancel the y. I'll do the latter:

$5x+2y=25\\\\2(5x-y=10)\\10x-2y=20$

Add from top to bottom:

$\rightarrow (5x+10x)+(2y-2y)=25+20\\\rightarrow 15x=45\\\rightarrow x=3$

Now, with the value of x, solve for y in either of the equations. I'll choose the second one here:

$\rightarrow 5x-y=10\\\rightarrow 5(3)-y=10\\\rightarrow 15-y=10\\\rightarrow -y=-5\\\rightarrow y=5$

(x, y) = (3, 5)
