Find two numbers, if Their sum is −7 and their difference is 14
Mademuasel [1]
Let
a------------> first number
b------------> second number

we know that
a+b=-7--------> a=-7-b----------> equation 1
a-b=14--------> equation 2

<span>I substitute 1  in 2
</span>
(-7-b)-b=14-------------> -7-b-b=14----------> -7-2b=14-------> 2b=-7-14
2b=-21---------> b=-10.5
a=-7-b-------> a=-7-(-10.5)-----> a=-7+10.5------> a=3.5

the answer is
the two numbers are 
a=3.5
and

Answer:

n = 13

Step-by-step explanation:

1. (9n-8) and (6n-7) combined equal 180 degrees, and we can translate that into an equation and then solve it: 9n - 8 + 6n- 7 = 180

2. (Solving)

Step 1: Simplify both sides of the equation.

  • (9n+6n)+(-8-7) = 180
  • 15n-15=180

Step 2: Add 15 to both sides.

  • 15n-15+15 = 180+15
  • 15n = 195

Step 3: Divide both sides by 15.

  • \frac{15n}{15}  = \frac{195}{15}
  • n = 13

Therefore, n = 13.
