Question

Me ajudem nessas equações
A) 3x-10=5
B) 2x-(-4)=10
C) 6-(-1x)=2
D) 5-(-3x)=1
E) 2x-2=10

Answer 1

A)

3x = 15

x = 5

B)

2x + 4 = 10

2x = 6

x = 3

C)

6 + 1x = 2

x = -4

D)

5 + 3x = 1

3x = -4

x = -4/3

E)

2x = 12

x = 6

Answer 2

Oie, Td Bom?!

A)

$3x - 10 = 5$

$3x = 5 + 10$

$3x = 15$

$x = \frac{15}{3}$

$x = 5$

B)

$2x - ( - 4) = 10$

$2x + 4 = 10$

$2x = 10 - 4$

$2x = 6$

$x = \frac{6}{2}$

$x = 3$

C)

$6 - ( - x) = 2$

$6 + x = 2$

$x = 2- 6$

$x = - 4$

D)

$5 - ( - 3x) = 1$

$5 + 3x = 1$

$3x = 1 - 5$

$3x = - 4$

$x = - \frac{4}{3}$

$x≈1,333...$

E)

$2x - 2 = 10$

$2x = 10 + 2$

$2x = 12$

$x = \frac{12}{2}$

$x = 6$
