Question

rezolvati in z ecuatile x•(-7)=14 , 35-x=23 , 4-3x=-35

Answer 1

X=14÷(-7)=-2
X=35-23=12
X=(-35-4)/(-3)=-39/(-3)=13 Am corectat am ajuns la 117 deoarece am inmultit in loc sa impart

Answer 2

x · ( -7 ) = 14
-7x = 14 ⇒ x = 14 / -7 ⇒ x = -2

35 - x = 23
-x = 23 - 35
-x = -12 ⇒ x = -12 / -1 ⇒ x = 12

4 - 3x = -35
-3x = -35 - 4
-3x = - 39 ⇒ x = -39 / -3 ⇒ x = 13
