3(10x + y) + 2x + 7y (multiply the 3 through the parentheses then combine like terms)
= 30x + 3y + 2x + 7y
= 32x + 10 y
Evaluate an expression for some values of x and y, means to substitute those values into the expression, such that
when x = 3 and y = 1 the value of the given expression is 106:
32x + 10y = 32(3) + 10(1) = 96 + 10 = 106
