Use elimination
Multiply first equation by 4
12a - 8b = 56
12a + 9b = 39
Subtract both
-17b = 17
b = -1
Plug in -1 for b
3a - 2(-1) = 14
3a = 12, a = 4
Final answer: a = 4, b = -1
Answer:
Option d.$18 to $30
Step-by-step explanation:
we know that
The quartet earn between $25 and $40 per hour.
so
If they play for 3 hours
then
($25*3)=$75
($40*3)=$120
the quartet will earn between $75 and $120
Divide the money equally between the four members
$75/4=$18.75
$120/4=$30
therefore
Each member can make between $18.75 and $30
