Answer:(-1,0)
Step-by-step explanation:
3x + 3y=-3. Solve by the elimination method.
-2x+y=2
2(3x + 3y)=-3(2) New equation 6x + 6y=-6
3(-2 + y)=2(3). New equation -6x +3y=6
9y= 0
y=0
6x +6(0)=-6
6x =-6
X=-1
(-1,0)
y=2x+2 *new equation for second*
3x+3(2x+2)=-3 *plug y into first equation*
3x+(6x+6)=-3 *combine like terms*
9x+6=-3 *bring 6 to the other side by subtracting 6 on both sides*
9x = -9 *divide by 9 to get x by itself*
x = -1
to find y (now that we have x):
-2(-1) +y=2
2+y=2
y=0
y=2x+2 *new equation for second*
3x+3(2x+2)=-3 *plug y into first equation*
3x+(6x+6)=-3 *combine like terms*
9x+6=-3 *bring 6 to the other side by subtracting 6 on both sides*
9x = -9 *divide by 9 to get x by itself*
x = -1
to find y (now that we have x):
-2(-1) +y=2
2+y=2
y=0
