| 7/8 x-10|<14
⚠Ⓘ 7/8 x-10|<14 is read as (7/8)*x-10|<14: use parentheses around the denominator to include the following factor in it
1) Let's solve in ℝ: |78·x -10| < 14
|7x8 -10| < 14
abs(A) < B means that: A < B and A > -B
2) Let's solve in ℝ: 7x8 -10 < 14
7x8 < 14 + 10
7x8 < 24
7x < 8·24
x < 8·247
Solution found: x < 1927
3) Let's solve in ℝ: 7x8 -10 > -14
7x8 > -14 + 10
7x8 > -4
7x > 8·(-4)
x > 8·(-4)7
Solution found: x > -327
Let's create the table of the different solutions to find the overall solution:
