x-5y=32......eq.1
2x%2B4y=-34.....eq.2
---------------------
start with eq.1 and solve for+x
x-5y=32
x=5y%2B32......eq.1

go to eq.2 and substitute x

2%285y%2B32%29%2B4y=-34.....eq.2, solve for y
10y%2B64%2B4y=-34
14y=-34-64
14y=-98
y=-98%2F14
y=-7

go to eq.1, substitute y
x=5%2A%28-7%29%2B32......eq.1
x=-35%2B32
x=-3
answer:
A. One solution:
ordered pair: (-3, -7)
