What is the solution to 8x - 3(2x - 4) = 3x - 18?

the answer is 3

Step-by-step explanation:

the answer is 3 implifying

8x + -3(2x + -4) = 18

Reorder the terms:

8x + -3(-4 + 2x) = 18

8x + (-4 * -3 + 2x * -3) = 18

8x + (12 + -6x) = 18

Reorder the terms:

12 + 8x + -6x = 18

Combine like terms: 8x + -6x = 2x

12 + 2x = 18

Solving

12 + 2x = 18

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-12' to each side of the equation.

12 + -12 + 2x = 18 + -12

Combine like terms: 12 + -12 = 0

0 + 2x = 18 + -12

2x = 18 + -12

Combine like terms: 18 + -12 = 6

2x = 6

Divide each side by '2'.

x = 3

Simplifying

x = 3

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg
