Answer:
x=14
Step-by-step explanation:
6(-6+x)=76-2x
Distribute
-36 +6x = 76 -2x
Add 2x to each side
-36+6x+2x = 76-2x+2x
-36 +8x = 76
Add 36 to each side
-36+36 +8x = 76+36
8x = 112
Divide by 8
8x/8 = 112/8
x=14
Answer:
40 CDs are by solo artists and 16 of the CDs are by female solo artists
Step-by-step explanation:
According to the question, Joshar has a collection of 1200 music CDs. He considers 1/6 of his collection rock music. Of the rock music CDs, 20% are by solo artists. Of the solo artists 2/5 are by female artists.
We are now asked to find many of the CDs are by solo artists and how many of the CDs are by female solo artists?
-----Joshar has 1200 music CD collection,
If 1/6 of his collection is rock music then the amount of rock music CD's with him is
1/6 × 1200
= 200
20% of the rock music CDs are by solo artists ie
20/100 × 200
= 40 CDs are by solo artists
Out of this 40 CD's, 2/5 of them are by female artists ie
2/5 × 40
= 16 are by female artists.

(x/-7) - 2 = 10
x/-7 = 12
x = -84
