Which of the following is a solution of y - x &lt; -3?<br><br> (6, 2)<br> (2, 6)<br> (2, -1)
Snowcat [4.5K]
Personally I'd solve this inequality for y first:  y < x-3.

That immediately eliminates (6,2) and (2,6).

Starting from y < x-3 and letting 2 sub for x and -1 sub for y, is the following true or false?

-1 < 2 -3     NO.  -1 < -1 is false.  Was there a fourth answer choice?

53 - 9y = 1<br> -7.2 + 2y = -5
telo118 [61]

Answer:

1.1, -5

Step-by-step explanation:

53 - 9y = 1

from equation i

53-9y = 1

-9y= 1-53 = -52

y = -52/-9= 52/9 = 5⁷/₉

-7.2 + 2y = -5

add 7.2 to both sides

2y= -5+7.2 = 2.2

y= 2.2/2 = 1.1
