Answer:
14w -14
Step-by-step explanation:
6w + 2(4w - 7)
Distribute
6w+ 8w -14
Combine like terms
14w -14
Amount spent on coffee= $70 - $48.31 = $21.69
Coffee cost $7.23 per pound
No of pounds of coffee bought = Amount in $ / Cost in $ per pound
= 21.69 / 7.23
= 3
3 pounds of coffee was bought
Answer:
x = 10
Step-by-step explanation:
2) -3x + 17 = -x - 3
4) 20 = 2x
1) -3x + 12 + 5 = -x -3
5) 10 = x
3) 17 = 2x - 3
<u>-3(x - 4) + 5 = -x - 3</u>
<u>-3x + 12 + 5 = -x - 3</u>
<u>-3x + 17 = -x -3</u>
<em>+3x +3x</em>
<u>17 = 2x - 3</u>
<em>+3 + 3</em>
<u>20 = 2x</u>
<u>10 = x</u>

Answer: The number of solutions to the given equation is zero.
Step-by-step explanation: We are given to find the number of solutions to the following equation :

To find the number of solutions, we must solve the given equation.
The solution of equation (i) is as follows :
which can never be possible.
So, the given equation has no solution.
Thus, the number of solutions to the given equation is zero.
