Answer:
Step-by-step explanation:
Equation
5y = 3y + 4
combine like terms 3y becomes negative when moved to the left side being that its positive on the right. 4 has no variable so it stands alone on the right side.
-3y + 5y = 4
After adding a low negative to a high positive number. Turns into 2y.
2y = 4
Divide 2 on both sides to remove the number from the variable on the left.
y = 
2 is canceled on the left side which gives the solution for Y.
y = 2
Answer:
A. 121
Step-by-step explanation:
The sum of the exterior angles is 360°, so you have ...
z + (z +10) + (z -13) = 360
3z -3 = 360 . . . . . collect terms
z -1 = 120 . . . . . . . divide by 3
z = 121 . . . . . . . . . add 1
