Question

what is the value of x? 3x = 16 - 5x

Answer 1

Solve for x:

3 x = 16 - 5 x

Add 5 x to both sides:

3 x + 5 x = (5 x - 5 x) + 16

5 x - 5 x = 0:

3 x + 5 x = 16

3 x + 5 x = 8 x:

8 x = 16

Divide both sides of 8 x = 16 by 8:

(8 x)/8 = 16/8

8/8 = 1:

x = 16/8

The gcd of 16 and 8 is 8, so 16/8 = (8×2)/(8×1) = 8/8×2 = 2:

Answer:  x = 2

Answer 2

Hi,

Work:

Equation;

$3x = 16 - 5x$

Move variable -5x to the left side and change its sign.

$3x + 5x = 16$

Collect like terms.

$8x = 16$

Divide both sides by 8.

$x = 2 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: result$

Hope this helps.
