Answer:
x2(y2 - 1) Now by using the identity a2 - b2. x2(y2 - 12) = x2(y + 1) (y - 1) Also, factorizing xy2 - 2xy - 3x by taking the common factor 'x' we get, x(y2 - 2y -
Step-by-step explanation:
Answer:
51 and 42
Step-by-step explanation:
Use
x + y = 93
x - y = 9
Add those two equations together and you get 2x = 102
*y is not in the equation anymore because y + -y = 0*
Divide both sides by 2
x = 51
plug x into one of the equations; let's use x + y = 93
Then you get, 51 + y = 93
Subtract both sides by 51 and you get y = 42
Plug both in the other equation to make sure the numbers work.
51 + 42 = 93; true
51 - 42 = 9; true
7 11/3 = 32/3 is my answer
Answer:
Fraction: -35/8
Decimal: -4.375
Step-by-step explanation:
Answer:
x = 9
Step-by-step explanation:
2(x+5)=3x+1
Distributive Property
2x+10=3x+1
Subtract 2x from both sides
10=x+1
Subtract 1 from both sides
9=x
Correct form: x=9
