Question

x +20 =3y/20+10=2z+5=110-(y+z) ​

Answer 1

Step-by-step explanation:

2x - 10 = 10 - 3x

Simplifying

2x + -10 = 10 + -3x

Reorder the terms:

-10 + 2x = 10 + -3x

Solving

-10 + 2x = 10 + -3x

Solving for variable 'x'.

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

Add '3x' to each side of the equation.

-10 + 2x + 3x = 10 + -3x + 3x

Combine like terms: 2x + 3x = 5x

-10 + 5x = 10 + -3x + 3x

Combine like terms: -3x + 3x = 0

-10 + 5x = 10 + 0

-10 + 5x = 10

Add '10' to each side of the equation.

-10 + 10 + 5x = 10 + 10

Combine like terms: -10 + 10 = 0

0 + 5x = 10 + 10

5x = 10 + 10

Combine like terms: 10 + 10 = 20

5x = 20

Divide each side by '5'.

x = 4

Simplifying

x = 4

Answer 2

$\frac{x + 20 = 3y}{20 + 10 = 2z + 5} = 110 - (y + z)$

$\frac{x + 10 = 3y}{10 + 10 = 7z} = 110y - 110z$

$\frac{x = 3y}{10 = 7z} = yz$

$x = 3 {y}^{2} z$

$10 = 7z \times 1$

$10 = 7z$

$10 - 7 = z$

$z = 3$

$x = 3 {y}^{2} z \\ z = 3$
