Answer:
-5 < x < 5
Step-by-step explanation:
|x| < 5
This can be split into two cases: x < 5 and -x < 5 because |x| could be either x or -x depending on whether x is positive, negative, or 0. Solving the second one we get x > -5 so the answer is -5 < x < 5.
Given equations are y = 7x − 8 and y = 5x − 2
We can solve them easily using substion.
Plug y = 7x − 8 into y = 5x − 2
7x − 8 = 5x − 2
or 7x − 5x =8 − 2
or 2x = 6
or 2x/2 = 6/2
or x=3
Now plug x=3 into any of given equations say y = 5x − 2
y = 5(3) − 2=15-2=13
Hence (3,13) is the final answer.
The correct answer is -70 if you substitute in -7 for c the equation will be = -63 -7 = -70
