Question

C) 4(x+1)=12 E) X/2-X/4=1/2

Answer 1

c) 4(x+1)=12
4x+4=12
4x=12-4
4x=8
x=8/4
x=2

Answer 2

c)

4 ( x + 1 ) = 12

4x + 4 = 12

4x = 12 - 4

4x = 8

x = 8 / 4

x = 2
________________________________________
e)
x/2 - x/4 = 1/2

mmc 2 e 4 = 4

2x/4 - x/4 = 2/4

x/4 = 1/2

x = 1/2 * 4

x = 4/2

x = 2
