Purple = p
Blue = b
Step 1: Write as an algebraic equation.
p = 4b - 6
p + b = 49
Step 2: Rearrange p + b = 49 to make p the subject.
p + b = 49
p = 49 - b
Step 3: Write p = 4b - 6 and p = 49 - b into one equation.
p = 4b - 6 = 49 - b
Step 4: Move all b values onto one side.
p = 5b = 55
Step 5: Find the value of one blue marble.
5b = 55
b = 11
Step 6: If there are 11 blue marbles and there are 49 marbles in total, then find the number of purple marbles.
p = 49 - b
p = 49 - 11
p = 38
