Question

30. Solve the equation below.
2
X- - 5 = 7
PLEASE HELP !!

Answer 1

2/3x -5=7

x=18

Explanation:

start by adding each side by 5

after doing so you should have

2/3x =12

multiply each side now my 3/2

the fractions should cancel out and leave x by itself

multiply (12)3/2

gives you 18.

x=18

Answer 2

9514 1404 393

Answer:

x = 18

Explanation:

Add the opposite of the constant (-5), and multiply by the inverse of the coefficient of x (2/3).

`(2)/(3)x -5=7\\\\(2)/(3)x=12 \qquad\text{add 5}\\\\x=(3)/(2)\cdot 12 \qquad\text{multiply by $(3)/(2)$}\\\\ \boxed{x=18}`
