(2x+15) +x=90
- 15 = -15
2x+x= 75
3x= 75
3 = 3
x= 25
1. 2 2/3
2. 4.2
Explanation:
1. 8/9*3=24/9=8/3=2 2/3
2. 9/5*7/3 9*7=63 5*3=15 so 63/15=21/5=4 1/5=4.2
The answer to that is -24a - 6
Use the quadratic formula to solve the equations . you will get the answers
Answer:
First you need to get your variable(x) by itself.
You do that by adding 16 to both sides of the greater than sign.
The 16 cancels or goes away. and 16 + 4 =20.
Your new equation is 20<4x
Finally you divide 20 by 4 to get 5
Your answer is 5<x or x>5.
