2/3(2x-1)+2 1/3=7+1/2x

schepotkina [342]

$Answer: x=4/5$

Step 1

$2/3*2*(2*x-1)-x+2*7-7*2 = 0\\5/3*x-14-4/3+14 = 0\\5/3*x-14+38/3 = 0$

Step 2

$5/3*x-4/3 = 0\\(5/3*x-4/3)/2 = 0\\(5/3*x-4/3)/2 = 0 // * 2\\5/3*x-4/3 = 0$

Step 3

$5/3*x-4/3 = 0 // + 4/3\\5/3*x = 4/3 // : 5/3\\x = 4/3/5/3\\x = 4/5$
