Question

y

Answer 1

1) 2x + 4 = 3x-11

(add 11 to both sides)

2x + 15 = 3x

(subtract 2x from both sides)

*****15 = x*****

2) 3x + 3 = 51

(subtract 3 from both sides)

3x = 48

(divide both sides by 3)

*****x = 16*****

3) 2x + 1/3 = x + 6/2

(6/2 is the same as 3..)

2x + 1/3 = x + 3

(3 can be expressed as 9/3)

2x + 1/3 = x + 9/3

(subtract 1/3 from both sides)

2x = x + 8/3

(subtract x from both sides)

*****x = 8/3*****
