Answer:

Step-by-step explanation:

Adding both equations will make it:

Putting x = 10 will make it:

= 3(1000)-40+1
= 3000-39
= 2961
Answer: x = -3.625 or -29/8
Step-by-step explanation:
7-8x+22
1. -Set it equal to 0.
7-8x+22=0
2. Subtract 7 and 22 from both the left and right sides.
7-8x+22=0
-7 -22 -7 -22
8x = -29
4. Divide both sides by 8.
8x=-29
8 8
x= -3.625
Leave it in fraction form if decimal is unacceptable.
