You can put this solution on YOUR website! Hello There:
Since there is only one equation, this is not a system of equations. I've moved your post to the linear equation section.
n - 4*(1 + 5*n) = -2
The goal is to isolate n on one side of the equals sign. Since the variable appears inside parentheses, we need to get rid of them. Use the distributive property to do this. Multiply both the 1 and the 5*n by -4.
n - 4 - 20*n = -2
Now we can combine the two terms containing the variable.
-19*n - 4 = - 2
Add 4 to both sides to isolate the term -19*n.
-19*n = 2
The last step is to divide both sides by -19. This solves the equation for n.
n = -2/19
