Question

What is the solotion to the equation 1/3(3+2x) -1=10

Answer 1

SOLVING:


`(1)/(3)(3+2x)-1=10\\ \\ (3)/(3)+ (2x)/(3)-1=10\\ \\1+ (2x)/(3)-1=10\\ \\ (2x)/(3)=10\\ \\2x=3(10)\\ \\2x=30\\ \\x= (30)/(2)\\ \\x=\boxed{ \boxed{15}}\ ===>\ The\ great\ answer.`

TESTING:

`(1)/(3)(3+2(15))-1=10\\ \\ (1)/(3)(3+30)-1=10\\ \\ (1)/(3)(33)-1=10\\ \\ (33)/(3)-1=10\\ \\11-1=10\\ \\\boxed{10}=\boxed{10}\quad\checkmark\ Correct.`
GOOD LUCK...!!!
