What value of x makes this equation true? 5+(2)/(3)x=-x+20 Type your answer...

To solve the equation $5+\frac {2}{3}x=-x+20$, we need to isolate the variable $x$ on one side of the equation.<br /><br />Step 1: Combine like terms on both sides of the equation.<br />$5+\frac {2}{3}x=-x+20$<br />$\frac {2}{3}x+x=20-5$<br />$\frac {5}{3}x=15$<br /><br />Step 2: Solve for $x$ by multiplying both sides of the equation by the reciprocal of $\frac {5}{3}$.<br />$\frac {5}{3}x=15$<br />$x=15\times\frac {3}{5}$<br />$x=9$<br /><br />Therefore, the value of $x$ that makes the equation true is $9$.
