Answer:
plain = $10.50
pepperoni = $12.50
Step-by-step explanation:
x = pepperoni
y = plain
3x + 2y = 58.5
2x + 4y = 67
using substitution method, I multiplied the first system by -2 to get:
-6x - 4y = -117
+ 2x + 4y = 67
-4x = -50
x = $12.50
2(12.5) + 4y = 67
25 + 4y = 67
4y = 42
y = $10.50
Answer:
There are no solutions
Step-by-step explanation:
−2(3x+4)−x+6=−5x−2(x+1)+5
(−2)(3x)+(−2)(4)+−x+6=−5x+(−2)(x)+(−2)(1)+5(Distribute)
−6x+−8+−x+6=−5x+−2x+−2+5
(−6x+−x)+(−8+6)=(−5x+−2x)+(−2+5)(Combine Like Terms)
−7x+−2=−7x+3
−7x−2=−7x+3
Step 2: Add 7x to both sides.
−7x−2+7x=−7x+3+7x
−2=3
Step 3: Add 2 to both sides.
−2+2=3+2
0=5
Answer - There are no solutions
