Question 862046
y=2x+1
3x-y=4
First, you can substitute 2x+1 for y in the second equation because y and 2x+1 are the same.
{{{3x-(2x+1)=4}}}
Distribute -1
{{{3x-2x-1=4}}}
Combine Like Terms
{{{x-1=4}}}
Add one to both sides
{{{x=5}}}
Substitute 5 into y=2x+1
{{{y=2(5)+1}}}
{{{y=10+1}}}
{{{y=11}}}
<h4>X=5 and Y=11</h4>
