Answer:
No solutions
Step-by-step explanation:
Let's solve your system by elimination.
10x − 9y = −10
20x − 18y = −28
Multiply the first equation by -2, and multiply the second equation by 1.
−2(10x − 9y = −10)
1(20x − 18y = −28)
Becomes:
−20x + 18y = 20
20x − 18y = −28
Add these equations to eliminate x:
0 = −8
