Solve for X: 12*2x=-24

A) 2
B) 0
C) -1
D) -2

x = -1

Step-by-step explanation:

Step 1: Divide both sides by 12

12 * 2x / 12 = -24 / 12

2x = -2

Step 2: Divide both sides by 2

2x / 2 = -2 / 2

x = -1

 x = -1

for the first question at the top, x=10

Step-by-step explanation:

x+3+9x=8x+23

(subtract 8x from both sides)

x+3+x=23

(combine the x terms)

2x+3=23

(subtract 3 from both sides)

2x=20

(divide by 2 from each side)

x=10
