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
49x^2 - 9 = 0
As there is no x term, we can pretty much guess we have a situation where we factlrise by something known aa difference of two squares, so to factorise it:
49 = 7^2
9 = 3^2
x^2 = (x)^2
so...
(7x - 3)(7x + 3) = 0
7x - 3 = 0 7x + 3 = 0
x = 3/7 x = -3/7
