Answer:
Y=60
Step-by-step explanation:
S+Y=90
S=(2*Y)-90
Y+2Y-90=90
3Y=180
Y=60
Plug back into S+Y=90
S+60=90
S=30
Answer:
No because whenever you plug in 2 into the x spots your answer is going to come out as positive one not -8.
Answer:
x = ±
Step-by-step explanation:
3x² - 9 = 0 ( add 9 to both sides )
3x² = 9 ( divide both sides by 3 )
x² = 3 ( take square root of both sides )
x = ±
or
3x² - 9 = 0 ← factor out 3 from each term
3(x² - 3) = 0
equate x² - 3 to zero and solve for x
x² - 3 = 0 ( add 3 to both sides )
x² = 3 ( take square root of both sides )
x = ±
