Answer: 7.867 x 10^8
Step-by-step explanation:
(the “^8” is an exponent of 8)
Solution
-6x - 3y = 9 Add 6x to both sides
-6x + 6x - 3y = 9 + 6x
-3y = 9 + 6x Or more conventionally
-3y = 6x + 9 Divide by - 3
y = 6x/-3 + 9/-3
y = - 2x - 3
5x+y = -23
by substitution
A)
5(-3) + (-4) = -23
-15 - 4 = -23
-19 = -23
Wrong
----------------
B)
5(-5) -3 = -23
-25 - 3 = -23
-28 = -23
Wrong
-----------------
C)
5(-4) - 3 = -23
-20 - 3 = -23
-23 = -23
