Answer:
Explanation:
Givens
Purple marbles = P
Red marbles = R
Equations
P + R = 114
P = 5*R + 6
Solution
Put the second equation into the first.
5*R + 6 + R = 114 Combine like terms on the left
6R + 6 = 114 Subtract 6 from both sides.
6R +6-6 = 114-6 Combine
6R = 108 Divide by 6
6R/6 = 108/6
R = 18
=======================
P+R = 114
P + 18 = 104 Subtract 18 from both sides.
P + 18-18=104 -18 Do the subtraction
P = 86
Answer: 7
