Answer:
x = - 6 , x = 4
Step-by-step explanation:
the absolute value function always gives a positive value but the expression inside can be positive or negative , that is
2x + 2 = 10 or - (2x + 2) = 10
solving both
2x + 2 = 10 ( subtract 2 from both sides )
2x = 8 ( divide both sides by 2 )
x = 4
or
- (2x + 2) = 10
- 2x - 2 = 10 ( add 2 to both sides )
- 2x = 12 ( divide both sides by - 2 )
x = - 6
Answer:
5
Step-by-step explanation:
-68x + p = qx + 34
p - 34 = qx + 68x <em>added 68x to both sides & subtracted 34 from both sides.</em>
p - 34 = x(q + 68)
The denominator cannot be equal to zero so q + 68 ≠ 0 ⇒ q ≠ -68
You didn't upload the options but look for the one that has q = -68.
