X+y=17 solve for a variable and plug into the 2nd equation
(x+3)/y=1 also could be written as x+3=y
x=17-y
17-y+3=y combine and add y over to other side
20=2y
y=10
plug back in x+10=17
x=7
so the original fraction is 7/10
Answer:
(2x + 1)(3x + 2)
Step-by-step explanation:
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 6 × 2 = 12 and sum = 7
The factors are + 3 and + 4
Use these factors to split the x- term
= 6x² + 3x + 4x + 2 ( factor the first/second and third/fourth terms )
= 3x(2x + 1) + 2(2x + 1) ← factor out (2x + 1) from each term
= (2x + 1)(3x + 2) ← in factored form
