Answer: x = 14
Step-by-step explanation:
-x+14 = 0
Subtract 14 from both sides of the equation :
-x = -14
Multiply both sides of the equation by (-1) : x = 14
This is a function, imagine if there were a line going up and down through every point, if one of those lines hits 2 points then it's not a function
Cupcakes =c
Drinks = d
22 c + 30d = $44.40...eqn 1
30c + 35d = $53.75...eqn 2
Multiply eqn 1 by 7 and eqn 2 by 6
154c +210d =$310.80...eqn 3
180c+ 210d = $322.5...eqn 4
Eqn 4 - eqn 3
26 c = $11.70
C = 11.7/26 = 45c
Subst c = 45c in eqn 1
$9.90 + 30d =$44.40
d = ($44.40-$9.90)/30 = $1.15
1/3 i hope this helps you!!
