Yung no.1 7x² - 63 = x² - 3x 
                 7x² - x² + 3x = 63
                 6x² + 3x = 63
              'di ko na alam sagot  sorry hahaha
yung no. 2  magiging y+5y-3y = -3   i-solve mo na yan madali nalang yan
yung no.3   di ko maintindihan equation :(
0
yung +1 tsaka 3x pagpalitin mo ng pwesto edi magiging -1 tapos - 3x bali 10/x - 3x = -1
Paano po pag 10 divided by 11 thirds?
ano yung 11 thirds? 'di ko alam sorry
11 over 3 po :)
ire reciprocal mo yung 11/3 bale magiging 3/11 tapos i multiply mo sa 10
