calcule encontrada as raizes das esquacaoes
A-x-15=20
B-4y+3=y-2
C-3x+12=24
D-5x+8=30
E-y-4=14
F-a+47=55
G-3x=21
H-4w=100
I-x-4=0
J-x+4=11

Answer 1

A) x = 20+ 15
X = 35

B) 4y - y = -2 - 3
3y= -5
Y = -5/3
Y = -1,666...

C) 3x = 24 - 12
X = 12/3
X = 4

D) 5x = 30 - 8
X = 22/5
X= 4,4

E) y= 14 + 4
Y= 18

F) a = 55 - 47
A= 8

G) x= 21/3
X= 7

H) w= 100/4
W= 25

I) x= 4

J) x = 11-4
X= 7
