Y=4x -1 and 12x=3y+7

1 answer:

4 0

You didn't really ask a question, so I'm assuming you want to know if there are any solutions to BOTH equations.

Use the first equation to substitute 4x - 1 for y in the second equation:

12x = 3(4x - 1)+7
12x = 12x - 3 + 7
12x = 12x +4
0 = 4

The last equation is FALSE, indicating the system of two equations has no solution.

EVELYN HAD 9 DOLLS, BUT SHE LOST 1/3RD OF THEM AT DAYCARE. HOW MANY TOTAL DOLLS WOULD EVELYN HAVE HAD IF SHE HAD NOT LOST THEM?

Elanso [62]

Answer:

Total Dolls would Evelyn have had if she had not lost them = 9 Dolls

Step-by-step explanation:

As given,

Total dolls Evelyn had = 9

If she had not lost te dolls , then she had 3 dolls more

∴ we get

If she had not lost any dolls , Evelyn had total dolls = 6 + 3 = 9

So, The answer would be :

Total Dolls would Evelyn have had if she had not lost them = 9 Dolls
