Let x be the smaller number. Then the larger number is (17-x). What the condition says about these numbers, is this equality 2*(17-x) = 3*x + 4. Simplify and solve this equation 34 - 2x = 3x + 4 34 - 4 = 3x + 2x 30 = 5x ======> x == 6. ANSWER. The smaller number is 6. The larger number is 17-6 = 11. CHECK. Twice the larger is 2*11 = 22; three times the smaller is 3*6 = 18; 22 - 18 = 4. ! Correct !
