3х — 7y = 21

Mathematics
1 answer:
Zolol [24]3 years ago
7 0
Answer:

Explanation:

3x - 7y = 21

6x = 14y + 42
Or 6x - 14y = 42

3x - 7y = 21 (1)
6x - 14y = 42 (2)
———————
-2(3x - 7y = 21)
6x - 14y = 42
———————
-6x + 14y = -42
6x - 14y = 42
———————
0x + 0y = 0

So I think in this case x and y has infinitely many solution

1.5d + 3.25 = 1 + 2.25d ---What are the steps to find x?
yuradex [85]
Do u mean d?

1.5d +3.25 = 1 +2.25d  
3.25 = 1 + .75d              -1.5d on both sides
2.25 = .75d                      subtraction 1 on both sides
3 = d                                  divide both sides by .75
