4x - 3y = 8 ⇒ 8x - 6y = 16
5x - 2y = -11 ⇒ 15x - 6y = -33
-7x = 49
-7 -7
x = -7
4x - 3y = 8
4(-7) - 3y = 8
-28 - 3y = 8
+ 28 + 28
-3y = 36
-3 -3
y = -12
(x, y) = (-7, -12)
To use elimination you have to multiply the first graph by 2 and the second graph by 3 so that the two y-axis can be equal to -6. Then you do the rest to find the answer of the x-axis and the y-axis.
-8 - 7x = -5x - 10....add 10 to both sides
2 - 7x = -5x ......NEXT STEP.....add 7x to both sides
Given:
$2.50 off any electronic book for an online bookstore.
let p = original price in dollars
d = discounted price in dollars
p = d + $2.50
The equation above is the working equation to determine the original and discounted price of any ebook purchased by Jason. <span />
