A certain test is worth 155 points. How many points (rounded to the nearest point) are needed to obtain a score of 65%?
Answers
3x + y = 17 and 4x - y = 18
Answers
I'm not sure if this is what you're asking for but here goes... 3x + y = 17 + 4x - y = 18 ——————— 7x = 35 x = 5
sub x = 5 into eq. 1 3x + y = 17 (3 × 5) + y = 17 15 + y = 17 subtract 15 from both sides of the equation. y = 2
Final Answer - ( 5 , 2 ) Hope this helped :)
