Given y=x+3 and y=2x+4.

Substitute y=2x+4 in y=x+3.

\begin{gathered} y=x+3 \\ 2x+4=x+3 \\ 2x-x=3-4 \\ x=-1 \end{gathered}

Put -1 for x in y=2x+4.Hence,

\begin{gathered} y=2x+4 \\ y=2\times(-1)+4 \\ y=-2+4 \\ y=2 \end{gathered}

Therefore, the value of x is -1 and the value of y is 2.

A stadium in Pennsylvanian seats 107,282 people. A stadium in Arizona seats 71,706 people. Based on these facts, how many more p
Blizzard [7]
Well, since we are finding out how many more seats there are in the Pennsylvanian stadium than in the Arizona stadium, we will have to subtract to find the difference. 107,282(pennsylvanian stadium) - 71,706(arizona stadium) would be 35,576 seats. So there would be 35,576 more seating in the Pennsylvanian Stadium than the Arizona Stadium.

A function f is defined by f(x) = 1 + 6x + x2 + 6x3 + x4 + ⋯ that is, its coefficients are c2n = 1 and c2n + 1 = 6 for all n ≥ 0
Alenkinab [10]

From the odd-degree terms, take out one copy and rewrite the series as

1+6x+x^2+6x^3+\cdots=(1+x+x^2+x^3+\cdots)+5x+5x^3+\cdots

1+6x+x^2+6x^3+\cdots=(1+x+x^2+x^3+\cdots)+5x(1+x^2+\cdots)

Then if |<em>x</em>| < 1, we can condense this to

\displaystyle\sum_{n=0}^\infty x^n+5x\sum_{n=0}^\infty x^{2n}=\frac1{1-x}+\frac{5x}{1-x^2}=\frac{1+6x}{1-x^2}

Since the series we invoked here converge on -1 < <em>x</em> < 1, so does this one.
