Solve for x. x − 2 > 2x + 12.
Roman55 [17]

Answer: ⇒ x

______________________________________________________

Step-by-step explanation:

First you had to add by 2 from both sides of equation.

x-2+2>2x+12+2

Simplify.

x>2x+14

Then you had to subtract by 2x from both sides of equation.

x-2x>2x+14-2x

Simplify.

-x>14

Multiply by -1 from both sides of equation. (it's going to be reverse by the inequality).

(-x)(-1)

Simplify it's should be the right answer.

x

Could you please show the work for both of them?​

7. y=-3/2x+8 (3rd answer choice)

substitute
-4=-3/2(8)+b
-4=-24/2 +b
-4=-12+b
+12 both sides
8=b

so equation would be...

y=-3/2x+8 (3rd answer choice)




8. y=-5x-17 (2nd answer choice)

substitute
-2=-5(-3)+b
-2=15+b
-15 both sides
-17=b

so the equation would be...

y=-5x-17 (2nd answer choice)


check your work by substituting each (x,y) value into the final equations if you want. hope this helps :))
