Hi all ..(adsbygoogle = window.adsbygoogle || []).push({});

How I can solve this two equations to get a and w0 ... ?

12 .5 = W0 + 10a ====== 1

20 = 10W0 + 5a ======= 2

--------------

this my trying ...

first I will multiply first equation with (-10) to remove the W0 then I will add both ..

-125 = -10W0 - 100 a

20 = 10W0 + 5a

--------------

-105 = -95 a

a = 1.1

is that correct ... ?
