Answer:

x > -2
n ≤ -2 or n ≥ 8

Step-by-step explanation:

Add 7x-2 to both sides and collect terms.

2x +2 -6x +7x -2 > -4 -7x +7x -2

3x > -6

x > -2 . . . . . . . divide by 3

Solve these one at a time, and form the union of the answers.

1 +7n ≤ 15 . . . .given

7n ≤ 14 . . . . . . subtract 1

n ≤ 2 . . . . . . . divide by 7

-2n -2 ≤ -18 . . . given

-2n ≤ -16 . . . . . add 2

n ≥ 8 . . . . . . . . divide by -2

The solution is n ≤ -2 or n ≥ 8.

What is the solution for the system of equations? y=−x+4 y= x−2

MissTica

Answer:

(3, 1 )

Step-by-step explanation:

Given the 2 equations

y = - x + 4 → (1)

y = x - 2 → (2)

Substitute y = x - 2 into (1)

x - 2 = - x + 4 ( add x to both sides )

2x - 2 = 4 ( add 2 to both sides )

2x = 6 ( divide both sides by 2 )

x = 3

Substitute x = 3 into either of the 2 equations and solve for y

Substituting into (2)

y = 3 - 2 = 1

solution is (3, 1 )
