Question 215269
Solve and check:
1) {{{8k+4 = 13}}}  Get the term with the variable, k, by itself by subtracting 4 from both sides of the equation.
{{{8k+4-4 = 13-4}}} 
{{{8k = 9}}} Now "undo" the multiplication on the left side by dividing both sides by 8.
{{{8k/8 = 9/8}}} Evaluate.
{{{k = 9/8}}} or {{{k = 1}}}{{{1/8}}}
