Answer:
x = - 4
Step-by-step explanation:
-79 = 7x + 3(4x - 1)
-79 = 7x + 12x - 3 Distribute 3 to the paranthesis
-79 = 19x - 3 Add like terms
-76 = 19x Add 3 to both sides
- 4 = x Divide 19 to both sides

</u>
Answer:

Step-by-step explanation:
<u>System of equations</u>
Kathy sells candles for $3 and flowers for $5. Let's set the following variables:
x = number of candles Kathy sells
y = number of flowers Kathy sells
She plans to sell 200 items, thus:
x + y = 200
She also likes to earn $2,500. The equation for this condition is:
3x + 5y = 2500
The system of equations is

12*12.5=150 oz 18*5=90 oz 150+90=240 convert to pounds = 15 pounds
