Question 1664: Solving the equation
Problem
4Y+7=5Y+13
I know the answer is -6
But I need a breakdown, when I first tried to complete this problem I subtracted 7 from both sides but I was left with 9Y (4Y+5Y), I just need a break down I am doing someting wrong.
Thanks

Oky-doke. Step-by-step:
4y+7=5y+13 Given
Invert the 5y.
-y+7=13
Invert the 7.
-y=20
Now divide the minus.
-y/- = 20/-
Your answer: y=-20
