I only know how to do number 1 so heres the answer 1) 1080
.6 is greater than .5 just like how 6 is greater than 5. If it's negative though, its the opposite!
hello :
<span>14ax-y+2ay-7x = (14ax+2ay) +(-y -7x) = 2a(7x+y) - (7x+y)
</span>14ax-y+2ay-7x = (7x+y)(2a - 1)
{4x - 5y = 17
{x - 5y = 8
{x = 5y + 8
{4(5y + 8) - 5y = 17
{x = 5y + 8
{20y + 32 - 5y = 17 | - 32
{x = 5y + 8
{15y = -15 | : 15
{y = -1
{x = 5 * (-1) + 8
{x = 3
{y = -1
