Question 268501
Please Complete the ordered pairs,(10) and (-10) , so that they satisfy the 
1/5x-1/10y=4 equation .
;
{{{1/5}}}x - {{{1/10}}}y = 4
Put the equation in the general y= form
Multiply by 10, get rid of the denominators, results:
2x - y = 40
-y = -2x + 40
multiply both sides by -1
y = 2x - 40
:
replace x with 10 to find y
y = 2(10) - 40
y = -20
Ordered pair 10,-20
:
replace x with -10
y = 2(-10) - 40
y = -60
Ordered pair: -10, -60
