w = 3(2a + b) - 4 Given w = 6a + 3b - 4 Apply the distributive property w - 6a = 3b - 4 Subtract 6a from both sides -6a = 3b - 4 - w Subtract w from both sides a = -3b - 4 - w / 6 Divide both sides by -6
<span>Shift the decimal points of both 25099.506 and 4.45 to the right by 2 decimal places. </span> <span>(This is needed to convert 4.45 to 445, since long division must divide by a whole number.) </span>
