Answer:

For the first test the score was 89 and on the second test it was 96

Explanation:

To find the answer we make the situation into an algebraic expression.


x + (x - 7) = 185 \\ 2x - 7 = 185 \\ 2x = 185 + 7 \\ 2x = 192 \\ (2x)/(2) = (192)/(2)

192 divided by 2 is 96; hence


x = 96 \\ x + (x - 7) = 185 \\ 96 + (96 - 7) = 185 \\ 96 + 89 = 185
