Question

2. Solve the following equations.
(i) 2(x – 3) = 14-3x
(ii) 5x +7(x - 2) = 3 - 4(x + 6)​

Answer 1

Answer:

Step-by-step explanation:

1) 2x - 6 = 14 - 3x

5x = 20

X = 4

2) 5x + 7x - 14 = 3 - 4x - 24

12x - 14 = - 4x - 21

16x = - 7

X= -7/16

Sorry if I'm wrong

Answer 2

Answer:

i. x = 4

ii. x = -7/16    ||  Decimal x = -0.4375

Step-by-step explanation:

i.

• 2(x - 3) = 14 - 3x

• 2x - 6 = 14 - 3x
• 2x - 6 + 6 = 14 -3x + 6
• 2x = -3x + 20
• 2x + 3x= -3x + 20 + 3x
• 5x = 20
• 5x/5 = 20/5
• x = 4

ii.

• 5x + 7(x - 2) = 3 - 4(x + 6)
• 5x + 7x - 14 = 3 - 4(x + 6)
• 12x - 14 = 3 - 4(x + 6)
• 12x - 14 = -4x - 21
• 12x - 14 + 14 = -4x - 21 + 14
• 12x = -4x - 7
• 12x + 4x = -4x - 7 + 4x
• 16x = -7
• 16x/16 = -7/16
• x = -7/16
