We have ax - bx = 1;
Then (a - b)x = 1;
If a - b is not 0, then x = 1 / (a-b);
2)
4x-10y=12
Subtract 4x from each side.
-10y=-4x+12
Divide both sides by -10
y=2/5x-6/5
3)
13=1/6y+2x
Subtract 2x from each side.
-2x+13=1/6y
Multiply both sides by 6.
-12x+78=y
Flip it around.
y=-12x+78
Hope this helps!
Answer:
C
Step-by-step explanation:
The answer is C.
12x+7x+8y+12^2+y+12=19x+9y+24^2
Hello!
1/4 is equal to 0.25. Let's divide below.
5/0.25=20
When dividing by fractions, you multiply by the reciprocal. The reciprocal of 1/4 is 4, and 5(4)=20
Therefore, our answer is 20.
I hope this helps!
