Solve 0.14x+0.08 (10'000-x) = 1220

College Intermediate Algebra

Solution

0.14x + 0.08 (10000 - x) = 1220 Remove the brackets.

0.14x + 800 - 0.08x = 1220 Combine like terms on the left

0.14x - 0.08x + 800 = 1220

0.06x = 1220 - 800 Subtract 800 from both sides

0.06x = 420 Divide by 0.06

x = 420 / 0.06

x = 7000 Answer
