2x - 3y = 3.....multiply by 4
5x - 4y = 4....multiply by -3
--------------
8x - 12y = 12 (result of multiplying by 4)
-15x + 12y = -12 (result of multiplying by -3)
-------------
- 7x = 0
x = 0 <===
The equation of a line is written as y = mx + b, where m is the slope and b is the y intercept.
You are given the slope: 5
The y-intercept is the y value when x is 0, this is also the point given to you (0,4), so the y-intercept (b) is 4.
The equation is y = 5x +4

Step-by-step explanation:
So add the number of chips together
5+3+7=15
So the chance of a red chip is 5/15
Blue 3/15
White 7/15
So the blue chips would be 3/15 chance
So take away one chip 14
So 7/14
The awnsers is
The probability of selecting a blue chip will be 3/15 and for a white chip it is 7/14
