$x=6$
Step 1. Let x represent one of the unknown quantities. $x$ = the number Step 2. Represent other unknown quantities in terms of x. $5x$ = five times the number Step 3. Write an equation in x that models the conditions. $5x-4=26$ Step 4. Solve the equation and answer the question. Add 4 to both sides: $5x-4+4=26+4$ $5x=30$ Divide both sides by 5: $x=6$ Step 5. Check the proposed solution in the original wording of the problem. if $x=6$ $5x-4=26$ $5(6)-4=26$ $30-4=26$ $26 = 26$ -->TRUE
