Answer:
Red: 161 White: 77
Step-by-step explanation:
Given there are 238 marbles in a jar, and there are 42 more red marbles than white marbles, we need to divide the number of marbles by two, as there are, presumably, two colors.
238 / 2 = 119
After doing this, we subtract 42 from one of the two 119s, and we add 42 to the other.
119 - 42 = 77
119 + 42 = 161
The value with 42 added is the red marble count, and the value with 42 subtracted is the white marble count.
