Answer:
Do you mean which equation should the 5x+10=15 be multiplied to?
it would be -2
Step-by-step explanation:
This is because 5 times -2 is -10
and so when you add the (now) x value of the first equation to the x value of the second equation, it gets 0
which makes it eliminated!
-10x+10x=0
Answer:
y = 3x - 8
Step-by-step explanation:
Line is passing through the points (2, - 2) & (0, - 8)
Slope of line

Answer:
Given Equation: y=5x-1
as we know that the y intercept have, x coordinate(absicasse) equal to 0
so,put x=0 to get y intercept
i.e, y =5×0 -1
i.e, y= <em><u>-</u></em><em><u>1</u></em>

Answer:

Step-by-step explanation:
2)
a) elimination method
b) substitution method
c) substitution method
For the first part we can elimate the y variable by subtracting the equations. We can then find the value of x.
For the second part we can substitute y as 2x+5 in the second equation and solve for x.
For the third part we can substitute y as 4x+3 in the first equation and solve for x.
