Answer 1

Answer:

1a. x=1/2              1b. x= 4

Step-by-step explanation:

1a. 30x= 16- 2x

(add 2x to both sides)

32x= 16

(divide both sides by 16)

x= 1/2

1b. 2(3x-5)=2x+6

(distribute the 2)

6x-10=2x+6

(add 10 to both sides)

6x=2x + 16

(subtract 2x from both sides)

4x= 16

(divide both sides by 4)

x=4
