Question

Am nevoie urgent cu ecuatii in R

Answer 1

Răspuns:

1.

x+15=24

x=24-15

x=9

x-37=4

x=37+4

x=41

x×8=10

x=10/8

x=5/4

x/7=4

x=7×4

x=28

2.

2x-7=3

2x=3+7

2x=10

x=10:2

x=5

-4x+5=0

-4x=-5

x=(-5)/(-4)

x=5/4

3x+4,5=0,5

3x=0,5-4,5

3x=-4

x=-4/3

3/2x+1/4=-1/2

6x+1=-2

6x=-2-1

6x=-3

x=-3/6

x=-1/2
