Answer:
The answer is (2x+3)(5x+2)
Answer:
=-1+\sqrt{15}i,\:x=-1-\sqrt{15}i
Step-by-step explanation:
Answer:
Let's solve your system by substitution.
x+y=−5;2x+2y=−5
Step: Solvex+y=−5for x:
x+y=−5
x+y+−y=−5+−y(Add -y to both sides)
x=−y−5
Step: Substitute−y−5forxin2x+2y=−5:
2x+2y=−5
2(−y−5)+2y=−5
−10=−5(Simplify both sides of the equation)
−10+10=−5+10(Add 10 to both sides)
0=5
