1/3x + 1/2 = -4
Here's how I would do it:
-- Multiply each side of the equation by 6x.
-- Subtract 3x from each side.
-- Divide each side by -27 .
That's how. When you solve it on your own, the solution is [ x = -2/27 ],
otherwise you've made a mistake and you should go back and correct it.
On the
necessary to ask for the steps if someone were solving it for you. Since
I'm only telling you 'how', as you requested, and not solving it for you, the
steps are all you're getting. This site doesn't do your homework for you.
You cannot solve one equation in three unknowns. You need three independent equations.
-3/10x = -9Multiply each side by 10x:-3 = -90xDivide each side by -90:x = -3/-90 = 1/30
18=3(3x-6)
Not sure that you can slove anything. -2w = r + s is one linear equation in 3 unknown variables. You need three independent equations in 3 variables to be able to solve them.
Add 2.9 to both sides. y = 8.2
5 -8
yes
You cannot solve one equation in three unknowns. You need three independent equations.
3-(-9) Considering a negative plus a negative equals a positive your equation can be rewritten as 3+9 Which equals 12
-3/10x = -9Multiply each side by 10x:-3 = -90xDivide each side by -90:x = -3/-90 = 1/30
18=3(3x-6)
To solve an equation with three unknowns, x, y and z, you require 3 independent equations.
Plugging the numbers into the equation gives b = -22.
the first step in solving the equation is to subtract the nine from the three. you will get negative 6.
