Find the smallest two consecutive even integers such that three times the smaller is at least 19 more than the sum of the two integers

3x - 19 = 2x + 2 Put all the constants on one side by adding 19 to both sides. 3x - 19 +19= 2x + 2 + 19 3x = 2x +21 Subtract 2x from both sides to have all the x's on one side. 3x - 2x = 2x +21 - 2x x
