Answer:
x=1
Step-by-step explanation:
Substitute the value of y to the first given
3x+4(-x)=-1
3x+(-4x)=-1
-x=-1
divide both sides by -1
x=1
Answer:
if you want to find which lines are parallel you must look at the slopes
Step-by-step explanation:
and you for this you must alone x
1) 3y=-x+5 slope is -⅓
2)3y=x-12 slope is ⅓
3)y=3x-2. slope is 3
4)6y=2x-7 slope is 2/6=⅓.
Finally the answer is 2 and 4 is parallel
A simple sentence contains one independent clause. A compound sentence contains more than one! Put another way: a simple sentence contains a subject and a predicate, but a compound sentence contains more than one subject and more than one predicate.
First you rewrite 1 2/3 into an improper fraction: z-1/3=5/3
Then you have: z-1/3=5/3
Move -1/3 to the right side of the equation by adding 1/3 to both sides.
z=1/3+5/3
Simplify the right side by combining the numerators over the common denominator: z=(1+5)/3
Add 1 and 5 to get 6: z=6/3
Divide 6 by 3 and get 2
z=2
