Answer:
y=-3x+9
Step-by-step explanation:
y=mx+b
m=slope
b=y-intercept
The answer is t = (y + 2n)/r
The expression is: rt - 2n = y
Rearrange it so that only rt is on the left side of the equation: rt = y + 2n
Rewrite the left side of the equation: r * t = y + 2n
Divide both sides of the equation by r: r * t / r = (y + 2n)/r
r can be cancelled out on the left side of the equation: t = (y + 2n)/r
Answer:
84
