Answer:
x = 18 or x = -12.
Step-by-step explanation:
||x-3|-5| = 10 only if |x-3|-5 = 10 or |x-3|-5 = -10, i.e., if |x-3|=15 or |x-3|=-5; but |x-3| cannot be equal to -5, because |x-3| should be a non-negative value. Therefore, the first equation is true only if |x-3|=15. |x-3| = 15 only if x-3 = 15 or x-3 = -15, i.e., x = 18 or x = -12. We can verify this in the following way: ||18-3|-5|=||15|-5|=|10|=10 and ||-12-3|-5|=||-15|-5|=|15-5|=|10|=10. This verify that our solution is correct.
The answer is k= -6 I just don’t know how to explain it to you!
Answer:
A. 2
B. 84
C. 18
Step-by-step explanation:
A. y ÷ 2 + x = 2 ÷ 2 + 1
= 1 + 1
= 2
B. z(x +y) = 6(6 + 8)
= 6(14)
= 84
C. 6q + m - m = 6(3) + 3 - 3
= 18 + 3 - 3
= 21 -3
= 18
