To solve the system of equations, we can use substitution or elimination. In this case, we can use substitution since the second equation is already solved for x.<br /><br />Given:<br />$2x+y=3$<br />$x=2y-1$<br /><br />Substitute the value of x from the second equation into the first equation:<br />$2(2y-1)+y=3$<br />$4y-2+y=3$<br />$5y-2=3$<br />$5y=5$<br />$y=1$<br /><br />Now substitute the value of y back into the second equation to find x:<br />$x=2(1)-1$<br />$x=2-1$<br />$x=1$<br /><br />Therefore, the solution to the system of equations is:<br />$(1,1)$
