<PRE><B>Question 628042</B>
10x + 75 = 150

Subtract 75 from each side of the equation

10x + 75 - 75 = 150 - 75

Combine like terms:

75 - 75 = 0

150 - 75 = 75

Therefore:

10x = 75

Divide each side by 10

10x/10 = 75/10

x = 15/2 = 7.5


The Answer:


x = 15/2 = 7.5</PRE>
