Answer: x= 5

Step-by-step explanation:

Plug the second equation into the first equation’s y.

Then use distribution

3x+4x-14=21

Add 4x and 3x

7x-14=21

Then add 14 to both sides

7x=35

Divide by 7 to get x

Simiplify without using absolute value bars, Solve for |x +7| for x>=7

Pavlova-9 [17]

Answer:

x +7

Step-by-step explanation:

The argument of the absolute value function is positive for any x > -7. The required domain is a subset of that, so the absolute value function does not change its argument.

|x+7| for x ≥ 7 is x +7
