• Equations with Brackets

Hint: To solve an equation containing brackets eliminate the brackets first, collect like terms on separate sides of the equation and then solve the equation.

### Example 4.2.2:

Solve the following equations:

i. 8(5p – 1) + 16 = 8(3p – 9)
ii. 2(2y – 5) – (y + 3) = 3(7 – y)
iii. 4(2x + 5) – 2(x – 3) – 8(2x + 4) = 0
iv. 0 = p + 2.5 – (3.6 – p)

Solution:

i. 8(5p – 1) + 16 = 8(3p – 9)

Expand the brackets

40p – 8 + 16 = 24p – 72

Collect like terms

40p – 24p = 8 -16 -72
