To solve the equation negative four equals two-fifths x, we can isolate x by multiplying both sides of the equation by the reciprocal of two-fifths, which is five halves.
Negative four * five halves equals two-fifths * five halves * x.
Simplifying, we get -10 = x.
Therefore, the solution to the equation is x = -10.
To solve the equation -4 = 2/5x, you can start by isolating the variable x.
To do this, you can start by multiplying both sides of the equation by the reciprocal of 2/5, which is 5/2.
(-4)(5/2) = (2/5x)(5/2)
Simplifying the left side of the equation gives you:
-20/2 = 1x
-10 = x
So, the solution to the equation is x = -10.
To solve the equation "negative four equals two-fifths x", or -4 = 2/5 x, you can follow these steps:
1. Start by isolating the variable x by getting rid of the fraction. To do this, multiply both sides of the equation by the reciprocal of 2/5, which is 5/2. This gives you:
(-4) * (5/2) = (2/5 x) * (5/2)
Simplifying, you have:
(-4)(5/2) = 1x
2. Calculate the left side of the equation:
-4 * 5/2 = -20/2 = -10
Therefore, the equation simplifies to:
-10 = x
So the solution to the equation is x = -10.
