PRECISA DOS CALCULOS PESSOA

Answer 1

A)3x - 4=12
3x = 12 + 4
3x = 16
x = 16/3
x= 5,3

B)19=4X-1
-4x = - 1 - 19
-4x = - 20
x = - 20/ -4
x = 5

C)2(X-1)=1=5
2x - 2 = 1 = 5
2x = 2 - 1 + 5
2x = 1 + 5
2x = 6
x = 6/2
x = 3

D)4(5-2X)=44
20 - 8x = 44
-8x = 44 - 20
-8x = 24
x = 24/-8
x = -3

(D )-3
(A )5,3
( B )5
(C )3
