Answer:
Step-by-step explanation:
⅓x + 7 = -2
isolate the x term by subtracting 7 from both sides
⅓x = -9
Multiply both sides by 3
x = -27
Answer:
x = -1 , y = 6
or (-1, 6)
Step-by-step explanation:
First solve for "y" in the second equation:

and now, use this result as a substitution for "y" in terms of "x" in the first equation:

Knowing the value of "x", now we place it in the substitution equation to find "y":

The answer will be 35 because it is a proportional side length
