1. if x=2y, find x and y
2. if x is 10 degrees more than twice y find x+y
3. find x+y if x is greater than y by 12 degrees
To find the values of x and y, we'll solve each equation step by step.
1. if x = 2y, we can substitute the value of x into the equation to find y. Rearrange the equation and solve for y:
x = 2y
Divide both sides by 2:
x/2 = y
Therefore, y = x/2
To find a specific value for x and y, we need more information.
2. if x is 10 degrees more than twice y, we can write the equation as:
x = 2y + 10
To find x + y, substitute the value of x into the equation:
(2y + 10) + y
Combine like terms:
2y + y + 10
Simplify:
3y + 10
Therefore, x + y = 3y + 10
Again, to find specific values for x and y, we need additional information.
3. If x is greater than y by 12 degrees, we can write the equation as:
x = y + 12
To find x + y, substitute the value of x into the equation:
(y + 12) + y
Combine like terms:
2y + 12
Simplify:
2y + 12
Therefore, x + y = 2y + 12
Once more, we require more information to determine specific values for x and y.
