7+l/5=-4
subtract 7 from both sides
l/5 = -11
multiply by 5
l = -55
(n/-3)-2=8
add 2 to both sides
n/-3 = 10
multiply by -3
n = -30
7+l/5=-4
(n/-3)-2=8
2 answers
a. 7+l/5=-4
You need to get l by itself on one side of the equation.
First step, move 7 to the opposite side of the equation by subtracting both sides by 7.
7+l/5=-4 (7 cancels on left)
l/5= -11 (multiply both sides by 5)
l=-55
b. (n/-3)-2=8 You need to get n by itself.
First step is to move -2 to the other side of the equation by adding it to both sides.
(n/-3)=10 (-2 cancels on left)
n=10*-3 (multiply both sides by -3, this will cancel -3 on the left.)
n=-30
You can plug these values back into the equation to check your answer at any time.
