Whats The Next Step To This:
2025a+45b=-1.39
324a+18b=1.81
Depends on the method.
For substitution, it could be
2025a + 45(1.81-324a)/18 = =1.39
For elimination, it could be
4050a+90b = -2.78
1620a+90b = 9.05
For any method it could be to reduce the size of the coefficients:
45a+b = -1.39/45
18a+b = 18.1/18
