X + 5y - 10 = 0
x = 2y - 8
Substitute the value of x in the 2nd equation to the 1st equation.
2y - 8 + 5y - 10 = 0
7y - 18 = 0 This is the resulting equation in its simplest form.
Find the value of y to get the corresponding value of x.
7y -18 = 0
7y = 18
y = 18/7
y = 2 4/7
x = 2y - 8
x = 2 (18/7) - 8
x = 36/7 - 8
x = 36/7 - (8 * 7/7)
x = 36/7 - 56/7
x = (36-56)/7
x = -20/7
x = -2 6/7
to check:
x + 5y - 10 = 0
-20/7 + 5(18/7) - 10 = 0
-20/7 + 90/7 - 10 = 0
-20/7 + 90/7 - (10 * 7/7) = 0
-20/7 + 90/7 - 70/7 = 0
(-20+90-70)/7 = 0
0/7 = 0
0=0

Answer:
<h2>Slope = 1/2</h2>
Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
From the question the equation is
- 5x + 10y = 20
To find the slope we must first write the equation in the form above
- 5x + 10y = 20
Move - 5x to the right side of the equation
10y = 5x + 20
Divide both sides by 10
We have
Comparing with the general form of equation above
Slope / m = 1/2
