por favor urgente ajudaa ​

Answer 1

A) 4x - 10 = 2x + 2

4x = 2x + 12

2x = 12

x = 6

B) 7( x - 1) - 2(x -5) = x - 5

7x - 7 - 2x + 5 =x - 5

5x =x - 5 + 2

4x = -3

x = -3/4

C) x/4 +7 = x/2 + 5

x + 7 × 2= x + 5 × 4

x + 14 = x + 20

x = x + 6

D) x - 1 / 5 = 2 x - 1 / 3

x - 1 × 3 = 2x -1 × 5

x - 3 =2x - 5

x - 5 = -3

x = 2
