Answer 2

the substitution method would be the best way to solve this...in my opinion
x - 2y = 10
x = 2y + 10
so we know that x = 2y + 10.....so sub in 2y + 10 for x back into the 1st equation
5x + 4y = 8
5(2y + 10) + 4y = 8
10y + 50 + 4y = 8
14y = 8 - 50
14y = - 42
y = -42/14
y = -3

now sub -3 in for y in either equation to find x
x - 2y = 10
x - 2(-3) = 10
x + 6 = 10
x = 10 - 6
x = 4

check...
5x + 4y = 8
5(4) + 4(-3) = 8
20 - 12 = 8
8 = 8 (correct)

so x = 4 and y = -3......or (4,-3)
