Question

solve the following equation​

Answer 1

Answer:

Step-by-step explanation:

→ [(4x + 4) - (7x - 8)] / 4x + 5 = -4/3

→ (4x + 4) - (7x - 8) = -4/3 × (4x + 5)

→ 4x + 4 - 7x - 8 = (-16x - 20)/3

→ 4x - 7x + 4 - 8 = (-16x-20)/3

→ -3x - 4 = (-16x-20)/3

→ -3x - 4 = -16x÷3 - 20÷3

→ -3x/1 - 4/1 = 16x÷3 - 20÷3

→ -3x/1 - 16x/3 = -20/3 + 4/1

→ (-3x * 3 / 1 * 3)  - (16x/3) = -20/3 + (4 * 3 / 1 * 3)

→ -9x/3 - 16x/3 = -20/3 + 12/3

→ -25x/3 = -8/3

→ 25x/3 = 8/3

→ 25x = 8/3 * 3

→ 25x = 24/3

→ 25x = 8

→ x = 8/25

Answer 2

Answer:

• (4x+4)-(7x-8)/4x+5 = -4/3

• 4x+4-7x+8/4x+5      = -4/3

• 12-3x/4x+5               = -4/3

• 3(12-3x)                    = -4(4x+5)

• 36-9x                       = -16x-20

• 16x-9x                      = -20-36

• 7x                             = -56
• x                                = -8
