Step-by-step explanation:

3(2x - 4) - 2(5x - 2) = -20

6x - 12 - 10x + 4 = -20

-4x - 8 = - 20

-4x = -20 + 8

-4x = -12

x = -12 ÷ -4

x = 3

In the diagram below segment DEF is shown(since all three letters are shown, they are collinear). If DE=3x+2, EF= x+5, and DF= 2

The value of $x$ is 4.

By Geometry, we know that line segment $DF = DE + EF$ , which is equivalent to:

$DF = 3\cdot x + 2 + x + 5$

$DF = 4\cdot x + 7$ (1)

Now we solve algebraically the resulting expression.

If we know that $DF = 23$ , then we solve the equation for $x$ :

$4\cdot x + 7 = 23$

$4\cdot x = 16$

$x = 4$

The value of $x$ is 4.
