Y = -5x + 9
y = 5x + 7

5x + 7 = -5x + 9
5x + 5x = 9 - 7
10x = 2
x = 2/10 reduces to 1/5

y = 5x + 7
y = 5(1/5) + 7
y = 1 + 7
y = 8

solution is (1/5,8)

Answer: v=-81.92

Step-by-step explanation:

$\displaystyle\\7+\frac{v}{8} =-3.24\\\\7+\frac{v}{8}-7 =-3.24-7\\\\\frac{v}{8} =-10.24\\\\\frac{v}{8} =-10.24$

Multiply both parts of the equation by 8:

$\displaystyle\\(\frac{v}{8})(8)=(-10.24)(8) \\\\v=-81.92$
