Elimination method. -2y = 0.5 - 2x<br> 6х + Зу = 6
AysviL [449]

Answer:

y=-1.5

X=1.75

Step-by-step explanation:

Yuh arrange the equations in order for easy subtracting of the equations.

-2y=0.5-2x. divide both sides by 2 to get y=-x-0.25.

6x+3y=6

3y=-6x+6 then divide both sides by three to get y

y=-2x+2

now arrange

y=-2x+2

y=-x-0.25 then multiple both equations by the cordinates of X value to eliminate x

How would I solve this and what would I get?
Nadusha1986 [10]
Answer: k1=-13/6 k2=19/6
to solve, move the constant to the right to get |3/10 - 3/5k| -0.4=1.2
next calculate to get |3/10 - 3/5k| 1.6
then separate into two equations to get |3/10 - 3/5k| 1.6
|3/10 - 3/5k| 1.6
then solve to get: k1=-13/6 k2=19/6
