Example: Solve the equation 5(x+1)βˆ’(6xβˆ’9)Γ·3=20+xβˆ’6 Solution: First simplify expressions on both sides of the equation:

Use distributive property to open parenthesis: 5x+5βˆ’(2xβˆ’3) = 20+xβˆ’6

5x+5βˆ’2x+3 = 20+xβˆ’6
Combine like terms: 3x+8 = 14+x
βˆ’x βˆ’x
2x+8 = 14
βˆ’8 βˆ’8
2x = 6
Γ·2 Γ·2
x = 3

x=3

Solve the equations :
Problem 1 : 5(2x βˆ’ 14) = 5x + 15
Answer :

Problem 5 : 94 = 5(2m + 2) + 2m
Answer :

Problem 2 : 4(y + 5) βˆ’ 3 = 6y βˆ’ 13
Answer :

Problem 6 : 3 + 4(6 + 5n) = 3(7n + 6)
Answer :

Problem 3 : 7(t βˆ’ 3) = 6(t βˆ’ 2)
Answer :

Problem 7 : 8 + f = 5f βˆ’ 5(f βˆ’ 9)
Answer :

Problem 4 : y βˆ’ 18 = 6(2 βˆ’ 3y + 10) + y
Answer :
