Question 208360
#14. Solve:
{{{15 = -3(2q-1)}}} First, divide both sides of the equation by -3.
{{{15/(-3) = (-3/-3)(2q-1)}}} Simplify.
{{{-5 = 2q-1}}} Add 1 to both sides.
{{{-5+1 = 2q-1+1}}} Simplify.
{{{-4 = 2q}}} Finally, divide both sides by 2.
{{{(-4)/2 = q}}} Simplify and put the variable (q) on the left side.
{{{highlight(q = -2)}}}
#22. Solve:
{{{x-5/8 = 7/8}}} Add 5/8 to both sides.
{{{x = 7/8 + 5/8}}}
{{{x = 13/8}}}
{{{highlight(x = 1.625)}}}
