1. x + 49 = -3x + 1
4x = -48
x = -12
2. 7x + 23 + 4x + 25 = 180
11x + 48 = 180
11x = 132
x = 12

Answer: 450
Step-by-step explanation:
971 = B + (T+71)
971-71 = 2 B
450 = B
The solution is x = 1 and x = -3
<em><u>Solution:</u></em>
Given that we have to solve the given equation by factoring
Given equation is:


Find a pair of integers whose product is c and and whose sum is b

Now find, a pair of integers whose sum is -2 and product is -3
The integers that satisfies this condition is -1 and 3
When we add - 1 and 3 we get 2
When multiply -1 and 3 we get -3
Thus the pair of integers are -1 and 3
Write the factored form using these integers.

The Zero Product Property states that if ab = 0, then either a = 0 or b = 0, or both a and b are 0
Set the factors equal to 0

x = 1 and x = -3
Thus the solution is x = 1 and x = -3
