Question

Resolva as equaçoes a seguir

A) 18x -43=65 B) 23x -16 = 14 - 17x

C) 2x + 4 = 10 D) 5 k - 12 = 20

E) 2Y + 15 - Y = 22 F) 9h - 2 = 43

Answer 1

A) 18x -43=65
18x=65+43
x= 108/18=6


B) 23x -16 = 14 - 17x
23x+17x=14+16
x=30/40= 3/4


C) 2x + 4 = 10
2x=10-4
x=6/2=3



D) 5 k - 12 = 20
5k= 20+12
k=32/5= 6,4



E) 2Y + 15 - Y = 22
2y-y=22-15
y=7


F) 9h - 2 = 43
9h= 43+2
h=45/9=5

Espero ter ajudado.

Answer 2

A) 18x= 108
X=108/18
X= 6

B) 23x + 17x = 14+ 16
40x = 30
X = 3/4

C) 2x = 10-4
2x = 6
x = 3

D) 5k = 20+12
5k = 32
k = 32/5

E) 2y - y = 22 - 15
y = 7

F) 9h = 43 + 2
9h = 45
h = 45/9
h = 5
