2x + 5 - 6x + 21 = 2(3x - 5) - 4
distribute
2x+5 -6x +21 = 6x-10 -4
combine like terms
-4x +26 = 6x -14
add 4x to each side
26 = 10x -14
add 14 to each side
40 = 10x
divide by 10
4 =x

Answer:
$2.00
Step-by-step explanation:
You can form an equation with these statements, x being the price of cheese pizza and y being the price of pepperoni. Making the equation,
3x+4y=18
3x+2y=12
Solving the equation,
3x+4y=18
6x+4y=24
-3x=-6
x=2
y=3
Solving another way,
2y=6
y=3
x=2
Therefore, the answer is $2.00
True!! If you multiply -3 x -7 you get 21!!
