2+a/-4=3/5 Two plus a over negative four equals three over five. please solve the problem
multiply both sides by -4
then subtract 2 from each side.
a=28/5
To solve the equation 2 + a/-4 = 3/5, you need to isolate the variable "a" on one side of the equation.
Let's start by multiplying both sides of the equation by -4, the denominator of the term a/-4. This will allow us to eliminate the fraction:
(-4) * (2 + a/-4) = (-4) * (3/5)
Simplifying, we have:
-8 - a = -12/5
Now, let's get rid of the negative sign in front of the "a" term by multiplying both sides of the equation by -1:
(-1) * (-8 - a) = (-1) * (-12/5)
Expanding the equation, we have:
8 + a = 12/5
Next, let's subtract 8 from both sides of the equation to isolate the variable "a":
8 + a - 8 = 12/5 - 8
Simplifying, we have:
a = 12/5 - 40/5
Now, we can subtract the fractions:
a = (12 - 40)/5
a = -28/5
Therefore, the solution to the equation is a = -28/5.
