Question

a) 3* (x - 2) = 24:
d) -2*(x-9)=28;
6) 8* (x+5) = 12;
e) -15 (x+6)=120;
c) 7* (x-5)=21;
f)-12-(x+10)= -96​

Answer 1

Răspuns:

Explicație pas cu pas:A)x-2=24/3

x=8+2

x=10

d)x-9=28/(-2)

x=-14+9

x=5

6)x+5=12/8

x=1,5-5

x=-3,5

e)x+6=120/(-15)

x=-8-6

x=-14

c)x-5=21/7

x=3+5

x=8

f)-12-x-10=-96

-x=-96+10+12

x=-74/(-1)

x=74
