Answer:
3x + 4y = -10
Step-by-step explanation:
Here, we want to select which of the options will give a system of two equations coupled with the first such that we have no solutions
Since we already have 3x + 4y = 10
The equation that will give a system leading to no solutions will be a system that equates the exact sum of 3x + 4y to another value
Mathematically, that will be;
3x + 4y = -10
