b. 3x + 9 =

c. 5x + 25 =

d. 5x - 25 =

Answer 1

$2x+16=\\2x=-16\\x=-16/2\\x=-8\\\\\\3x+9=\\3x=-9\\x=-9/3\\x=-3\\\\\\5x+25=\\5x=-25\\x=-25/5\\x=-5\\\\\\5x-25=\\5x=25\\x=25/5\\x=5$

Answer 2

A)

2X+16 =

2X = -16

X = -16/2

X = -8

B)

3X+9 =

3X = -9

X = -9/3

X = -3

C)

5X+25 =

5X = -25

X = -25/5

X = -5

D)

5X-25 =

5X = +25

X = +25/5

X = +5
