Answer:
6x + y = 1
y = 1 - 6x
7x + 2(1 - 6x) = -3 substitute 1 - 6x in for y
7x + 2 - 12x = -3 combine like terms
2 - 5x = -3 subtract 2 from both sides
-5x = -5 divide by -5
x = 1
Answer:
0
Step-by-step explanation:
Distribute:
=(6)(3x)+(6)(−5)+(2)(3x)+(2)(−5)+(−8)(3x)+(−8)(−5)
=18x+−30+6x+−10+−24x+40
Combine Like Terms:
=18x+−30+6x+−10+−24x+40
=(18x+6x+−24x)+(−30+−10+40)
=0

Step-by-step explanation:
I was answering the question and got it correct
Answer:
1)
2/5 ≠ 10/15= 2/3 not equivalent
3/7 ≠ 6/7 not equivalent

= 9/7 equivalent
2)
a) 50/75 = 25*2/25*3= 2/3
b) 65/105 = 5*13/5*21= 13/21
c) 18/81 = 9*2/9*9= 2/9
