Using the quadradic formula to solve x^2=5-x, what are the values of x

For this case we must solve the following equation:

By manipulating algebraically we have:

The quadratic formula is given by:

We have to:

Substituting we have:

So, we have two roots:

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this
