Question 1135264
<br>
If the two equations are both in the form Ax+By=C, then elimination is nearly always easier than substitution.<br>
{{{8A+5C = 180.5}}}
{{{12A+6C = 261}}}<br>
Multiply the first equation by 3 and the second by 2.  That will make the coefficients of A both 24; then subtracting one equation from the other will eliminate A and let you solve for C.<br>
{{{24A+15C = 541.5}}}
{{{24A+12C = 522}}}
{{{3C = 19.5}}}
{{{C = 6.5}}}<br>
Substitute the value you found for C back in one of the original equations to solve for A.<br>
{{{8A+32.5 = 180.5}}}
{{{8A = 148}}}
{{{A = 18.5}}}<br>
