What is the answer of this equation ? 10x-6(2x+5)=20
Rudiy27

Answer:

Simplifying

x = -25

Step-by-step explanation:

Reorder the terms:

10x + -6(5 + 2x) = 20

10x + (5 * -6 + 2x * -6) = 20

10x + (-30 + -12x) = 20

Reorder the terms:

-30 + 10x + -12x = 20

Combine like terms: 10x + -12x = -2x

-30 + -2x = 20

Solving

-30 + -2x = 20

Solving for variable 'x'.

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

Add '30' to each side of the equation.

-30 + 30 + -2x = 20 + 30

Combine like terms: -30 + 30 = 0

0 + -2x = 20 + 30

-2x = 20 + 30

Combine like terms: 20 + 30 = 50

-2x = 50

Divide each side by '-2'.

x = -25

Find the equation of a line that has a slope of 1/2 and passes through the origin.
omeli [17]

Step-by-step explanation:

The equation of a line with slope m and y-intercept b is y = m x + b.  

This line goes through the point ( 0 ,0 ), so the y-intercept is zero.

We are given the slope as − 2 / 3.

The equation of the line is y= – 2 / 3 x + 0 = – 2 / 3 x

y = – 2 / 3 x
