The sum of all the angles of a triangle is 180 degrees. To solve for y you can make a formula of the sum of the angles equal to 180 like so...
y + y + 60 = 180
Now you must combine like terms. This means that first numbers with the same variables (y) must be combined...
y + y + 60 = 180
y + y = 2y
2y + 60 = 180
Now bring 60 to the left side by subtracting 60 to both sides (what you do on one side you must do to the other). Since 60 is being added on the left side, subtraction (the opposite of addition) will cancel it out (make it zero) from the left side and bring it over to the right side.
2y + 60 - 60 = 180 - 60
2y + 0 = 120
2y = 120
Next divide 2 to both sides to finish isolating y. Since 2 is being multiplied by y, division (the opposite of multiplication) will cancel 2 out (in this case it will make 2 one) from the left side and bring it over to the right side.
2y / 2 = 120 / 2
y = 60

Step-by-step explanation:
x-19=1/2x+6
50-19= 31
50/ 1/2 = 25 + 6 = 31

Step-by-step explanation:
add 41; d = 60
Answer:
the answer is 6
Step-by-step explanation:
you take the absolute value for both of them which is 2 and 8 but you keep the negative still so it would be -2+8 which is 6
