Question

ax4+35+ax6=ax5+ax10

 

Answer 1

a x 4 + 35 + a x 6 = a x 5 + a x 10

a x (4 + 6) + 35 = a x (5 + 10)

=> a x 10 + 35 = a x 15

=> 35 = a x 15 - a x 10

=> 35 = a x (15 - 10)

=> 35 = a x 5

=> a = 35 : 5

=> a = 7

Answer 3

Ta có: 4a + 35 + 6a = 5a + 10a

<=>    10a + 35 = 15a

=>       35 = 15a - 10a

=>       35 = 5a

=>         a = 35 : 5

=>         a = 7
