Question 25039
Solve for a:
{{{(2a/4) - 31 = 4(2 + 8a)}}} I hope this is correctly copied. Simplify the fraction on the left side.
{{{(a/2) - 31 = 4(2 + 8a)}}} Multiply through by 2 to to clear the denominator.
{{{a - 62 = 8(2 + 8a)}}} Simplify the right side using the distributive property.
{{{a - 62 = 16 + 64a}}} Subtract 16 from both sides of the equation.
{{{a - 78 = 64a}}} Subtract a from both sides.
{{{-78 = 63a}}} Divide both sides by 63.
{{{-78/63 = a}}} Reduce the fraction.
{{{a = -26/21}}} or, in decimal form:
{{{a = -1.24}}}
