7x+2=23
Move 2 to the other side
7x=23-2
7x=21
To isolate the x divide both sides by 7
x=3
To check plug the value of x back in
7(3)+2=23
21+2=23
23=23
Answer:
With all or just 1
Step-by-step explanation:

Substituting this into the other ODE gives

Since
, it follows that
. The ODE in
has characteristic equation

with roots
, admitting the characteristic solution

From the initial conditions we get



So we have

Take the derivative and multiply it by -1/4 to get the solution for
:

Answer:
The error is when 6y = 12 it will be -6y = 12 and the intercept would be -2.
Step-by-step explanation:
Slope ~3
y intercept ~7
y= equation ~y=3x+7
