Using the elimination method to solve this system of equations problem 3x + 4y = 12 and -3x - 2y = 6, name its solution. *
1 answer:
Answer: x=-8 and y=9
Step-by-step explanation:
3x +4y=12 ( This can be equation 1)
-3x-2y=6 ( This can be equation 2)
Equation 1 + equation 2 = 2y=18
y= 18÷2
y=9
Substitute 9 for y in 3x+4=12
3x+4y=12
3x+4(9)=12
3x+36=12
3x= 12-36
3x=-24
x= -24÷3
x= -8
Therefore x=-8 and y=9

Reflection line of reflection y=2
Not too sure could be rotation maybe
Combine like terms
8u+3u= 11u
and
9v-5v= 4v
So the answer is 11u+4v
Domain is x values... Y is y values
