Answer: x=-303
Step-by-step explanation:
x+310=7
We move all terms to the left:
x+310-(7)=0
We add all the numbers together, and all the variables
x+303=0
We move all terms containing x to the left, all other terms to the right
x=-303
Answer:
X = -8 and X = 2
Step-by-step explanation:
X^2 + 6X - 6 = 10
Bring the 10 over:
X^2 + 6x - 16 = 0
From here, either use the quadratic formula or
manual factorization by finding its roots:
Manually:
(X + 8)(X - 2) = 0
Equate each factor to 0 you will get:
X + 8 = 0 and X - 2 = 0
Solutions are -8 and 2 respectively.
