# How do you solve the simultaneous equations #3r - 2t = -0.2# and #r + s = 2.4#?

##### 1 Answer

#### Answer:

You can not solve for the values of 3 variables with only 2 equations;

however, if the second equation was meant to be

#### Explanation:

The best we could do with 2 equations with 3 unknowns is generate a linear relationship between two of the variables:

For example, by solving for

and

So

If however the equations were meant to be (in only two variables):

[1]

[2]

Multiplying [2] by 2:
