All value less than -6 make that inequality true
8x+1=x-6
7x+1=-6
7x=-7
X=-1
Y=x
Y=-1
Answer:
Y=-3/2
Step-by-step explanation:
-2y+3=-4y
Move constant to the right by adding its opposite to both sides
-2y+3-3=-4y-3
Eliminate the opposites
-2y=-4y-3
collect the like terms
-2y+4y
collect the like terms
(-2+4)y
Calculate the sum
2y=-3
divide both sides of the equation by 2
2y÷2=-3÷2
Any expression divided by itself equal 1
y=-3÷2
y=-3/2
