Answer 2

Answer:

x = - 3

Step-by-step explanation:

Given the 2 equations

y = $\frac{1}{3}$ x + 7 → (1)

y = 3x + 15 → (2)

Since both equations express y in terms of x, equate the right sides

3x + 15 = $\frac{1}{3}$ x + 7

Subtract $\frac{1}{3}$ x from both sides

$\frac{8}{3}$ x + 15 = 7 ( subtract 15 from both sides )

$\frac{8}{3}$ x = - 8 ( multiply both sides by 3 )

8x = - 24 ( divide both sides by 8 )

x = - 3
