So if simplified it would be
-3x+15=15-3x
Which is basically the same thing if arranged
15-3x=15-3x
-3x+15 can also be 15-3x still the same thing as adding 15 to -3x
So since these are equal anything could be used
like try 0
Both get 15
Try 1
Both get 12
Try legit any number
youll get the same results (I would choose 3 positive easy ones, 0,1,2 and 3 negative ones -1,-2,-3)
Answer: y = -5; x = -2
Step-by-step explanation:
- 5y – 10x=45
- 3y + 10x = -5
Combining both equations
-8y = 40
y= 40/ -8
y = -5
Substitute y = -5 into any of the equations to get the value of x
-5 (-5) - 10x = 45
25 -10× = 45
-10x =45 -25
-10× = 20
Divide both sides by -10
x = -2
