Question

: (2x – Зу = 18 (2x + y = 2

Answer 1

Answer:

y = -4

x = 3

Step-by-step explanation:

I will be using the elimination method to solve this:

Begin by times -1 to the bottom equation.

$2x-3y=18$

$-2x-y=-2$

Add them together

$0x-4y=16$

ignore the 0x and divide -4 to both sides

$\frac{-4y}{-4} =\frac{16}{-4}$

y = -4

Plug y back into one of the two original equations

$2x-3(-4)=18$

multiply -3 and -4 to get +12

$2x+12=18$

subtract 12 to both sides

$2x=6$

divide by 2 to both sides

x = 3

Answer 2

Answer:

2x = 2 × 12 = 24 24 =2x 24-6=18

3y = 3 × 2 = 6 6 =3y

2x = 2×1 = 2 2 =2x 2+0=2

y = 0 0 = y

I'm not sure how the question is mentioned in the test but from my point of view I got this not sure how the it is explained in your nest im only 11 so yeh. sos if its wrong
