Answer:
x = 3 and x = -12
Step-by-step explanation:
To solve an absolute value equation, you create two equations, one where the right side is negated and one where the right side isn't:
| 2x + 9 | = 15 becomes:
2x + 9 = 15 and 2x + 9 = -15
2x = 6 and 2x = -24
x = 3 and x = -12
Why this works is that |-x| and |x| will both be equal to 0. Remember that absolute value is the distance a number is away from 0.
Answer:
find the least common multiple for the denominator and multiply with the numerator
for the first one,
Step-by-step explanation:
the common multiple for 4 and 6 is 12
4×3=12
6×2=12
multiply the same numbers with the numerator
1×3=3
5×2=10
the answer is 3/12 and 10/12
The second yes is the answer
6×9=57
