Answer:
It requires of two equations
Step-by-step explanation:
example:
2x +7y = 12
Answer: 5/6
Change 1/2 into 3/6 and 1/3 into 2/6 and add them together.
Answer:
n = 14
Step-by-step explanation:
7(n + 1) -2(4n-3) = -1
7n + 7 -8n + 6 = -1
-n + 13 = -1
-n = -14
n = 14
Since the two equations equal y, set them equal to each other.
x-1=-2x+5
From there, solve for x.
First get x on one side, by using the addition property of equality.
x-1=-2x+5
3x-1=5
Isolate x by adding 1.
3x=6
Lastly get x all by itself by dividing each side by 3.
x=2
You can now substitute your x-value, 2, into one of the equations (or both, if you wish; either one will result in the same answer.)
y=x-1
y=2-1
y=1
OR
y=-2x+5
y=-2(2)+5
y=-4+5
y=1
Final answer:
x=2 and y=1
