Answer:
7 x = -35
Step-by-step explanation:
Which equation results from adding the equations in this system? 11 x minus 3 y = -17. Negative 4 x + 3 y = - 18.
- 7 x = negative 35
- 7 x = 35
7 x = negative 35
7 x = 35
In this problem we need to add the equations below i.e.
11x-3y = -17 and -4x+3y=-18
Adding both equations,
11x-3y+(-4x)+3y = -17+(-18)
7x= -35
or
7 x = negative 35
Hence, the correct option is (c).
Answer:
Ameliorate retort, pertaining to preceding albeit contingent interrogate proximates subject to x = 12.
Step-by-step explanation:
Availing, exploiting, albeit maneuvering the Mathematic convention, Order of Operations (OO), the contiguous albeit proximate equation may ascertain as the preeminent imminent:
Groups: Not identified.
Exponents: Not identified, disparaging ₁.
Multiplication: Derived, pertaining to subtraction, 4 · (7/4x) = 4 · 21 <u>7x = 84</u>
Division: Derived, pertaining to multiplication, 7x = 84 ⇒ <em><u>x = 12</u></em>
Addition: Aggregate constants ⇒ 5/2x = 3/4x +21
Subtraction: Abate algebraic groups ⇒ 7/4x = 21
