Answer:
the pair solution is : (10;5)
Step-by-step explanation
d + e = 15
....(1)
–d + e = –5
....(2)
add (1) and (2) : 2e =10
e = 5
put the value of : e in (1) or (2) : d + 5 = 15
d = 10
In linear functions (mx+b), the m is the slope, therefore the -2 is the slope.

Given equation: 3(x + 4) + 2 = 2 + 5(x – 4).
<em>First step is to distribute 3 on left side and 5 on right side of the equation,</em> we get
3x + 12 + 2 = 2 + 5x – 20
<em>Second step is combining like terms, 12+2=14 and 2-20=-18.</em>
We get
3x +14 = 5x -18.
<h3>Third step, we need to get rid 18 from right side and 3x from left side.</h3>
<em>Adding 18 on both sides and subtracting 3x from both sides</em>, gives
32 = 2x.
<h3>Fourth step , we need to get rid 2 from right side from 2x.</h3>
<em>We need to divide both sides by 2</em>, we get
16=x.
