Respuesta :

x + 2 (2x + 20) = 85
x + 4x + 40 = 85
5x + 40 = 85
5x = 45
x = 9

12y + 6 + 32y = 2y - 6y - 30
44y + 6 = -4y -30
48y = -36
y = -36/48
y = -3/4

The values by solving the linear equation is

1.  x = 9

2. y = -3/4

What is linear equation?

A linear equation only has one or two variables. No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction.

Given equation :

1. x + 2 (2x + 20) = 85

or, x + 4x + 40 = 85

or, 5x + 40 = 85

or, 5x = 45

or, x = 9

2. 12y + 6 + 32y = 2y - 6y - 30

or, 44y + 6 = -4y -30

or, 48y = -36

or, y = -36/48

or, y = -3/4

Hence, the value of x is 9 and y is -3/4.
