Answer:
649
Step-by-step explanation:
Given the expression :
__ ÷ 18 > 86
Let blank = y
y ÷ 18 > 36
y / 18 > 36
Multiply both sides by 18
(y / 18) * 18 > 36 * 18
y > 648
Hence, the least whole number which can make the statement true is (648 + 1) = 649

Step-by-step explanation:
<u>Step 1: Define Systems</u>
y = x - 4
y = 4x + 2
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: x - 4 = 4x + 2
- Isolate <em>x </em>terms: -4 = 4x + 2
- Isolate <em>x</em> term: -6 = 4x
- Isolate <em>x</em>: -3/2 = x
- Rewrite: x = -3/2
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define equation: y = x - 4
- Substitute in <em>x</em>: y = -3/2 - 4
- Subtract: y = -11/2
