Y - 2x = 8 . . . . . . . . (1)
16 + 4x = 2y . . . . . .(2)
From (1), y = 8 + 2x
substituting for y into (2), we have
16 + 4x = 2(8 + 2x) = 16 + 4x
0 = 0
Therefore, there are an infinite number of solutions

Can someone help me on this plzzz
choli [55]

Answer:

b=15

How I got it:

32 + (7x4) = 32 + 28 = 60

60 divided by 4 = 15

Checking:

15 - 7 = 8

8 x 4 = 32

32 = 32

<em>You can tell b = 15 is the correct answer.</em>

Please help me :) please
dangina [55]

Answer:

In bold.

Step-by-step explanation:

6/6 = 9/a

So a = 9.

6/c = a/4.5

6/c = 9/4.5 = 2

So c = 3.

By similar triangles:

d/5 = 6/ (6+6+3)

d/5 = 6/15 = 2/5

So d = 2.

Also by similar triangles

b/5 = 12/15 = 4/5

So b = 4.
