Hey everybody, i really need some help quick.
Im having trouble with linear equations. If anyone can show me how to solve them that would be great.
3x + 5y = 26
2x - y = 13
x - 2y = -12
3x + 8y = 34
I also need help on these.
2x - 3y = 4
.02x + .01y = .52
Last but not least...
Terry did all 25 problems on the test and got an 85. Scores are computed by giving 4 points for each right answer and subtracting 1 point for each wrong answer. How many problems did Terry get right and wrong?
