X=popcorn
x - 3.50=drink
2x+ 4(x-3.50)=32.50
2x+4x-14=32.50
solve for x
Answer:
a) 0≠ -10
b) x= -3
c)y= 0
Step-by-step explanation:
a) 3-4x=-7-4x

So, this equation has no solution as both sides are not equal.
b) 
Solving:

So, this equation has one solution
c) 7(y-3)=6y-21
Solving:

So, this equation has one solution.
1. Write equation with no solution. 3-4x=-7-4x (check solution of a)
2. Write equation with one solution. 7(y-3)=6y-21 (check solution of c)
3. Write equation with infinite solution. 2x + 3 = x + x + 3
solving:
2x+3=2x+3
2x-2x+3=3
3=3
When both sides are equal, the equation has infinite solutions.

Answer:
40
Step-by-step explanation:
You would first want to plug in.
10 x (-1)² x (-2)²
Now apply the exponents.
10 x 1 x 4
Now combine.
40
Answer:
Step-by-step explanation:
