Question

Alguien me ayuda porfa​

Answer 1

a) 6 = x + 2

6 - 2 = x

4 = x

b) 8 + 3x = 4x + x

8 = 4x + x - 3x

8 = 2x

8/2 = x

4 = x

c) x + x + x + x = x + 5 + x

x + x + x + x - x - x = 5

4x - 2x = 5

2x = 5

x = 5/2 ó 2.5

d) 9 + x + 3x = 7x + 2x + x

9 = 7x + 2x + x - x - 3x

9 = 10x - 4x

9 = 6x

9/6 = x

3/2 ó 1.5 = x
