Okay so you have 2 equations. so take one and solve for y. ex: y=3+2x
the next equation that involves the y put that in replace of it for ex: 2y=3+3x
2(3+2x)=3+3x
6+4x=3+3x
then solve per usual.

Answer:
Step-by-step explanation:
The temperature T(d) in degrees Fahrenheit in terms of Celsius d is given by:
And the temperature C(v) in degrees Celsius in terms of Kelvin v is given by:
We want the formula for the temperature F(v) in degrees Fahrenheit in terms of the Kelvin temperature.
So, we can use a composition of functions. Since T(d) outputs the temperature in Fahrenheit and C(v) inputs the temperature in Kelvin, T(C(v)) will be the temperature in Fahrenheit given the temperature in Kelvin. So:
Substitute:
Therefore:
Answer: Yes, it does because linear equations are straight lines, this means the degree of a linear equation must be 0 or 1 for each of its variables. For y=5x, the degree of variable y is 1 and the degree of variable x is 1.
