Answer:
y= -3/5x - 1/5
Step-by-step explanation:
The slope formula:
y=mx+b
m = slope, which is -3/5 in your case
b= your y-intercept, which is -1/5 in your case
Simply plug it in and you get your answer.
x = 3 + y Eqn(1)
y = -2x + 9 Eqn(2)
Let us solve the system of equations with the substitution method
x - 3 = y (Subtracting 3 from both sides of the Eqn(1))
Replacing y = x - 3 in Eqn (2), we have:
x - 3 = -2x + 9
x = -2x + 9 + 3 (Adding 3 to both sides of the equation)
x + 2x = 9 + 3 (Adding 2x to both sides of the equation)
3x = 12 ( Adding like terms)
x = 12/3 (Dividing by 3 on both sides of the equation)
x = 4
Replacing x=4 in Eqn(1), we have:
4 = 3 + y
4 - 3 = y (Subtracting 3 from both sides of the equation)
y=1
The answers are:
x= 4 and y=1
You cant factor by 9 because 15 cant be factored by 9. you can factor it by 5 and get 18x - 3 might want to check my answer

Pizza is 12. Sandwich is 8. Total for both is 20.
92-68=24
24/3=8
8*4=32
68-32=36
36/3=12
