Answer:
-8
Step-by-step explanation:
(x-3y=136) + (18x+3y=288) We collect both processes to make y's disappear
19x=-152
x=-8
Answer:
x = ± 4
Step-by-step explanation:
given 3x² = 48 ( divide both sides by 3 )
x² = 16 ( take the square root of both sides )
x = ±
= ± 4
x ∈ {- 4, 4 }
D since (-5 x -5) = 25 and (7 x -8) = -56. Add 25 and -56 and your answer is D. -31
