Question 1055426
The sum of half a number and 49 is 9/2 of the number
<pre>
Substitute x for the words "a number" and "the number".
</pre>
The sum of half x and 49 is 9/2 of x
<pre>
Substitute {{{expr(1/2)x}}} for "half x"
</pre>
The sum of {{{expr(1/2)x}}} and 49 is 9/2 of x
<pre>
Substitute {{{expr(9/2)x}}} for the words "9/2 of x"
</pre>
The sum of {{{expr(1/2)x}}} and 49 is {{{expr(9/2)x}}}
<pre>
Substitute {{{expr(1/2)x+49}}} for the words "The sum of {{{expr(1/2)x}}} and 49"
</pre>
{{{expr(1/2)x+49}}} is {{{expr(9/2)x}}}
<pre>
Substitute an equal sign " = " for the word "is":
</pre>
{{{expr(1/2)x+49}}}{{{""=""}}}{{{expr(9/2)x}}}
<pre>
Subtract {{{expr(1/2)x}}} from both sides:
</pre>
{{{49}}}{{{""=""}}}{{{expr(9/2)x-expr(1/2)x}}}

{{{49}}}{{{""=""}}}{{{expr(8/2)x}}}

{{{49}}}{{{""=""}}}{{{4x}}}

Divide both sides by 4

{{{49/4}}}{{{""=""}}}{{{x}}}
