Answer:
your question is really not clear but if you were to put the -4 in the Y then the answer would be X=1/3, if you plug in -4 for X and find Y then Y = -17
Step-by-step explanation:
plug in -4 in Y
-4=3x-5 add 5 on both sides,
1 = 3x divide 3 on both sides
1/3= x
plug in -4 in X
y = 3(-4)-5 multiply 3 and -4 = -12
y = -12-5 subtract the -12 and -5 = -17
y = -17

Answer:
<em>(-8,4)</em>
Step-by-step explanation:
<u>System of Equations:</u>
Solve the following system of equations by the substitution method:
5x - 6y = -64 [1]
y = 20 + 2x [2]
Substituting y from [2] in [1]:
5x - 6(20 + 2x) = -64
Operating:
5x - 120 - 12x = -64
Simplifying:
-7x - 120 = -64
Adding 120:
-7x = -64 + 120 = 56
x = 56/(-7) = -8
x = -8
From [2]:
y = 20 + 2(-8) = 4
Solution (-8,4)
