First, let's multiply the first equation by two. This is because we have to eliminate either x or y by subtraction or addition so that means either both of the x's or both of the y's in the two equations have to be equal. Thus multiplying the first equation by 2 will give 12x+8y=4.
Next, subtract equation two from equation one:
We get a third equation, 2x-0= -28
Thus, x=-28/2. x= -14
In the same way, to find y, we need to eliminate the x's in both equations. This can be done by multiplying the first equation by 5 and the second by 3
Thus : 30x+20y=10 and 30x-24y=96
Subtracting the second equation from the first, we have 0+44y=-86
y=-86/44
y = 1.96 or 43/22
Hey! So I’m pretty sure you multiply 56 and 2, then you swap the sides of the equation. Answer: X=112
Answer:
below..
Step-by-step explanation:
- slope = (y - y1)/(x-x1) = (6 - 3 )/(1-0) = 3 is the slope/ gradient
- equation of the line = y -3 = 3(x - 0) => y = 3x + 3
Answer:
Step-by-step explanation:
5/8
you need to add all numerators, same denominator
Answer:
1:1
Step-by-step explanation:
The ratio would be 1:1 since it's a square, the sides will always be the same. In a square ,all sides are the same length. If they are not, then it wouldn't be a square.
