If: 4x = 5y Then: x = 5y/4

(-5, 2)
5y + x = 0 subtract 5y from each side, then x = -5y
y = -6
If: 4x = 5y Then: x = 5y/4
7
(-5, 2)
x = (-5y + 4) / 7
5y + x = 0 subtract 5y from each side, then x = -5y
y = -6
x = 0 and y = 4
9y
It equals x+5y simplified
Answer : x = 6 : y = -4.62x = 12 therefore x = 6 : substituting in x - 5y = 29 gives :-6 - 5y = 29 : 5y = 6 - 29 = -23 : y = -23/5 : y = - 4.6
x + 5y = 10 5y = -x + 10 y = -x/5 + 2 m = -1/5 or .2
x - 5y = -4 x + 8y = -4 The first equation gives x = 5y - 4 SUBSTITUTE this value for x in the second equation: (5y - 4) + 8y = -4 Simplify: 13y = 0 so that y = 0 Then x = 5y - 4 gives x = -4
