The correct answer is A, or x + 1 = 4x + 5. We used the substitution method to replace y with x + 1.
Use distributive property:
7 ig because I mean if you take a look at the problem
X^2 + 10 = 35 when x = -5
x + x + x = 3x = -15 when x = -5.
The answer is B because part A just restates the first equation, and Part C determines which is greater. If you want to determine the difference between the two when x = -5, part B is the best answer because it subtracts the product of one of them from the other.
