Question

(

Student scored 7 points
less on the 1st Test than
he did on 2nd test,
Total score is 185 what
are scores on each test

Answer 1

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`
