X^2 + y^2 - x^2 +y^2
That would be (1x+1y)-(1x+1y)
Answer:
y = 56/3
Step-by-step explanation:
We need to write equations to solve
Let the two numbers be x and y
The sum is 56
x+y = 56
The first number is 2 times greater than the second number.
x = 2*y
Substitute this into the first equation
x+y = 56
2y+y=56
3y = 56
y = 56/3
Answer:
-7
Step-by-step explanation:
2x +3 =x-4
2x - x =-4 - 7
x=-7
