The answer would be D.
you would start by choosing one of the variables to eliminate, i chose to eliminate X first. in order to eliminate X, i had to multiply the second equation by -2. X then cancelled out, and i solved for the Y the same way you would a 1 step equation. Y=-4
I then took the first original equations, plugged Y in, and solved for X. X=3.

Hope this helps!

Split £20 in the ratio 2:3

ValentinkaMS [17]

Hi friend,

The objective is to divide $20 in 2:3 ratio.

One part be 2x, another part is 3x

Sum of them = 20

2x + 3x = 20

5x = 20

x=4

So therefore one part must be 2x = 2 x 4 = 8

Another part = 3x = 3 x 4 = 12

Hence it is divided in 2:3 ratio.

Hope my answer is helpful to u. :)

Starting from the y-intercept of $\displaystyle [0, 2],$ you do $\displaystyle \frac{rise}{run}$ by either moving two blocks north over three blocks west or two blocks south over three blocks east [west and south are negatives].
