14x + 7 = 30
Step-by-step explanation:
Given
7y + 6 = 36 and y = 2x + 1
substitute y = 2x + 1 into 7y + 6 = 36 , that is
7(2x + 1) + 6 = 36 ( subtract 6 from both sides )
7(2x + 1) = 30 ← distribute parenthesis on left side by 7
14x + 7 = 30
(x – h)² + (y – k)²<span> = r</span>²
Fill in the numbers
(x – 7)²<span> + (y +3)</span>²<span> = 49</span>
