4(16) = 4(10+6) = 40 + 24 = 64
-4x + 3(2x - 5) = 31 (use distributive property to remove parentheses)
-4x + 6x - 15 = 31 (combine like terms)
2x - 15 = 31 (add 15 to both sides)
+15 +15
2x = 46 (divide both sides by 2)
x = 23
The variables are x and y. The constant is 250. The coefficients are 14 and 3
