Since <span><span>−y</span></span> does not contain the variable to solve for, move it to the right side of the equation by adding <span>y</span> to both sides.<span>x=<span>y+<span>30</span></span></span>
Match each label to the correct location.
5/8 * 4/5
5*4 20 1
----- = ----- = ---
8*5 40 2
5/8 * 4/5 = 1/2 or .5
4(4x + 5)
4(4•7+5)
4(28+5)
4(33)
