Step-by-step explanation:
2x - 3y = 25
+ (5x + 3y = 10)
=> 7x = 35, x = 5.
Therefore 2(5) - 3y = 25, 3y = -15, y = -5.
The solution pair is (5,-5).
B. I think I’m really not sure that’s confusing as hell and I’ve passed that
2x2+5x=12, 2x+5x=7x, 12+2=14, 7x/7=14/7, x=2
Answer: you multiply the 2 numbers and divide it by half then your answer is the easy way to do it.
