Question

# The sum of 4 consecutive integers is 70. Then the greatest among them is ________________.A) 19B) 23C) 17D) 16

Hint: There is no set order, as the steps used depend on what is given:
We may add, subtract, multiply, or divide an equation by a number or an expression as long as we do the same thing to both sides of the equal sign. Note that we cannot divide by zero.
Apply the distributive property as needed: $a(b + c) = ab + ac.$
Isolate the variable on one side of the equation.
When the variable is multiplied by a coefficient in the final stage, multiply both sides of the equation by the reciprocal of the coefficient.

$\Rightarrow (x) + (x + 1) + (x + 2) + (x + 3) = 70\;{\text{ }}\;$
$\Rightarrow 4x + 6 = 70\; \\ \Rightarrow 4x = 64 \\ \Rightarrow x = 16 \\$
