b=3a+2a 2a=18b
Substitute 2a for x in the second and third equation.
a=\frac{1}{5}b b=\frac{1}{9}a
Solve these equations for a and b respectively.
b=\frac{1}{9}\times \frac{1}{5}b
Substitute \frac{1}{5}b for a in the equation b=\frac{1}{9}a.
b=0
Solve b=\frac{1}{9}\times \frac{1}{5}b for b.
a=\frac{1}{5}\times 0
Substitute 0 for b in the equation a=\frac{1}{5}b.
a=0
Calculate a from a=\frac{1}{5}\times 0.
x=2\times 0
Substitute 0 for a in the equation x=2a.
x=0
Calculate x from x=2\times 0.
x=0 a=0 b=0
The system is now solved.
