Solve by canceling -5x+8y=-4 6x-8y=-12

Mathematics
1 answer:
Vinil7 [7]3 years ago
7 0

Step-by-step explanation:

-5x+8y=-4

6x-8y=-12   8y and 8x cancel out

         x=-16

To solve for y, substitute x=-16 back into the first equation

-5(-16)+8y=-4

    80+8y=-4

          8y=-84

            y=-10.5

How many solutions exist for the given equation? 0.75(x 40) = 0.35(x 20) 0.35(x 20) zero one two infinitely many
zimovet [89]

Answer:

One solution

Step-by-step explanation:

0.75 (x + 40) = 0.35 (x + 20) + 0.35 (x + 20)

0.75x + 30 = 0.35x + 7 + 0.35x + 7

0.75x + 30 = 0.7x + 14

0.05x + 30 = 14

0.05x = -16

x = -320

Hope this helps!
