2. Which of the systems of equations below could not be
used to solve the following system for x and y?
6x + 4y = 24
-2x + 4y = -10
A
6x + 4y = 24
2x - 4y = 10
B
6x + 4y = 24
- 4x + 8y = -20
18x + 12y = 72
-6x + 12y = -30
D
the
12x + 8y = 48
-4x + 8y = -10

thats a hard on

Step-by-step explanation:

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

2,160 π
