( 4х+3)-(10х+11)=7+(13-4х)

Question

( 4х+3)-(10х+11)=7+(13-4х)

Answer 1

(4x + 3) - (10x + 11) = 7 + (13 - 4x)

4x + 3 - 10x + 11 = 7 + 13 - 4x

4x - 10x + 4x = 7 + 13 - 3 - 11

-2x = 6

x = 6 : (-2)

x = -3

 

Мы сейчас такие же проходим :)

Answer 2

(4х+3)-(10х+11)=7+(13-4х)

4x-10x+4x=7+13-11-3

-2x=6

x=-3
