You cannot solve one equation in three unknowns. You need three independent equations.
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
If you mean: 10ac -x/11 = -3 then a as the subject is a = (-33+x)/110c
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
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.
