Hello!
Let's solve this question by using elimination.
5x + 10y = 7
4x + 8y = 3
Let us solve for "y" first by making our "x" variables cancel each other out.
4(5x + 10y = 7)
-5(4x + 8y = 3)
20x + 40y = 28
-20x -40y = -15
0 = 13
Since both the "x" and "y" variables were canceled out after trying to eliminate one of the variables, we can't find a solution since we now have no variables to solve for, therefore there is no solution.
Answer: No solutions
