3x-2y=4 ---> Multiply -2
-6x+4y=-8
-6x+4y=-8
6x-2y=-2
+_______
6x-6x+4y-2y=-8-2
2y=-10
y=-5
for y=-5;
3x-2y=4
3x-2*(-5)=4
3x+10=4
3x=4-10
3x=-6
x=-2
Answer:
Your answer is Division Property of Equality
Step-by-step explanation:
It <em>could</em> be Addition Property of Equality, but the second number shows it is actually the division property of equality. Here's my work:
-4x + 6y = 12 Given
(-4x/2) + (6y / 2) = (12/2)
--Simplify--
−2x + 3y = 6

Answer:
x=2/3
Step-by-step explanation:
(1/2)/3=x/4
(1/2)(1/3)=x/4
1/6=x/4
cross product,
6*x=1*4
6x=4
x=4/6=2/3
x=2/3
