Question

Q9. Solve the following simple equation
(i) -6x /5 + 2x /15 = -4 ​

Answer 1

$\frac{ - 6x}{5} + \frac{2x}{15} = - 4 \\ \frac{ - 18x + 2x}{15} = - 4 \\ \frac{ - 16x}{15} = - 4 \\ - 16x = - 60 \\ x = 3.75 \: or \: \frac{15}{4}$

Answer 2

Answer:

x = 15/4 or 3.75

Step-by-step explanation:

-6x/5 + 2x/15 = -4

Equalize the denominators

-6x*3/ 5*3 + 2x/15 = -4

-18x /15 + 2x/15 = -4

-16x /15 = -4

-16x = 15*-4

-16x = -60

16x = 60

x = 60/16

x = 15/4 or 3.75
