Question 21238
2x/7 + 3x/2 = 25/7
So then lets use the common denominator of 14, so we get;
{{{(2)2x/14}}}+{{{(7)3x/14}}}={{{25/7}}}
{{{4x/14}}}+{{{21x/14}}}={{{25/7}}}
Now we can add 4+21;
{{{25x/14}}}={{{25/7}}}
Now we will multiply 14 to both sides;
(14){{{25x/14}}}={{{25/7}}}(14)
That will leave use with;
25x={{{350/7}}}
Let's dovde 350/7=50
25x=50
Now we divide each side by 25;
{{{25x/25}}}={{{50/25}}}
x=2
You'll get it and graduate!
