Answer:

x = -1

Step-by-step explanation:

30 = 2.5(10)(-2x)  - you multiply by each

30 = 25 - 5x        - then pass 25 to the other side and subract

5x = - 5x               - then divide 5 / -5

Answer:

x= -1

Step-by-step explanation:

distribute 2.5 through the parenthese

30=25-5x

move variable to the left hand side an change its sign

5x+30 =25

move constant to the right hand side and change the sign

5x=25 -30

calculate the difference

5x= -5

divide both sides of the equation by 5

x= -1

Hope this helps!!! I would really appreciate a brainliest???
