This equation simplified would be 2x^2.
Since we have terms that are not like (one has a variable and the other doesn't), we simply put them together when being multiplied.
x^2 * 2 = 2x^2
Answer:
x is equal to -9 thus it becomes -18 in the whole setup
Answer:
I believe the answer would be c
Step-by-step explanation:
I am terribly sorry if i am wrong. if I am, please tell me in the comments so I can fix it
y=-3x+4
x=2y+6
y + 3x =4
-2 + =6
x= 2y +6
y+3.(2y+6)=4
7y = -14
7y=-14
y=-2
y=-2
x=2y+6
x=2(-2)+6=2
solution is {y,x}= {-2,2}
