Reggie lost three spaceships in level 3 of a video game he lost 30 points for each spaceship when he completed level three heat earned a bonus of 200 points by how much did his score change.

His score change was 110

Step-by-step explanation:

Lets say he started at 0 points and lost 30 points for each spaceship thats 3 x 30 which is 90 so he's sitting at -90 points then got 200 so thats -90 + 200 = 110

you can't solve x because it is 2 linear equation and you only have one equation
