No solution
Step-by-step explanation:
-x + y = 3
-3x + 3y = 4
Multiply top by -3

Answer:
Hello, so the answer is 21.
Step-by-step explanation:
Okay so first we want to do it order, so the order you do it in is the order of PEMDAS which stands for Parentheses, Exponents, Multiplication, Division , Addition and Subtraction.
So in this situation we have parenthesis, multiplication, subtraction and addition, so we start with the parenthesis, (8 x 3) which is 24. So then we move on to +6 (positive six) and -9 (negative 9) basically -9 minus 6 is -3.
Sooo now we have -3 and 24. The three is negative because -9 minus 6 is -3, and you have to put the sign of the bigger number.
Now, 24 minus 3 equals 21. So there we have it :)
Hope I helped!
The answer would be Light
Speed= distance/time
Therefore, time= distance/speed.
t=225 miles/25 mph= 9 hours
Final answer: 9 hours
Answer:
y = 3
Step-by-step explanation:
9 - y = 2y
+ y + y Add y to both sides
9 = 3y Divide both sides by 3
3 = y When y = 3, the value of 9 - y is twice the value of y.
