Answer:

Step-by-step explanation:

Here, we want to solve the system of linear equations by substitution

We can substitute by making 2.5y the subject of the formula in the first equation

We have this as:


2.5y\text{ = 0.3x + 2.4}

We substitute this into the second equation as follows:


-0.3x\text{ + 0.3x + 2.4 = 3.4}

From here, we can see that the 0.3x will cancel out and we will not be able to proceed

What this simply tells us is that the system of lnear equations has no solution
