How do you solve #2y+2=5y+9#?

Answer 1

Kennedy Adams

Combine like terms and solve for y

#- 2 1/3#

# 2y + 2 = 5y + 9#

Combine #2y and 5y# by subtracting #2y# from both sides.

# 2y - 2y + 2 = 5y - 2y + 9 " "# This gives

# +2 = 3y + 9" " # This gives

# -7 = 3y" " # Divide both sides by 3

# -7/3 = (3y)/3 #

# - 2 1/3 = y#

To solve the equation 2y + 2 = 5y + 9:

Subtract 2y from both sides: 2 = 3y + 9
Subtract 9 from both sides: -7 = 3y
Divide both sides by 3: y = -7/3
