Multiply both sides by 2. Collect like terms in the LHS. Divide both sides by the coefficient on the variable.

the equation is x + 1/2 * x = 10

strategy is as follows:

place all values of x under a common denominator.

x + 1/2 * x = 10 becomes 2/2 * x + 1/2 * x = 10

combine like terms.

2/2 * x + 1/2 * x = 10 becomes 3/2 * x = 10

multiply both sides of the equation by the reciprocal of the fraction.

3/2 * x = 10 becomes 2/3 * 3/2 * x = 2/3 * 10

simplify the equation by performing the operations indicated.

2/3 * 3/2 * x = 2/3 * 10 becomes x = 20/3

confirm the solution is correct by replacing the value of x with its value.

x + 1/2 * x = 10 becomes 20/3 + 1/2 * 20/3 = 10

simplify the equation further by performing the operations indicated.

20/3 + 1/2 * 20/3 = 10 becomes 20/3 + 10/3 = 10

combine like terms.

20/3 + 10/3 = 10 becomes 30/3 = 10

perform a final simplification.

30/3 = 10 becomes 10 = 10

test to see if the equation is true.

10 = 10 is true.

report the solution.

x = 20/3
