Answer:

(0,3)

Step-by-step explanation:

Step 1: 7x-2y=-6 Step 2: 7x-2y=-6 solve by elimination of the y value

2(8x+y=3)2 +(16x+2y=6)

Step 3: 23x=0, which means <u>x=0</u>

Step 4: subtitute 0 into the equation 8x+y=3

you get 8(0)+y=3, which comes to 0+y=3

you get <u>y=3</u>

therefore the solution to this system is (0,3)

Answer:

Step-by-step explanation:

1/2(x)=7/2

divide both sides by 1/2

x= $\frac{7}{2}$ ÷ $\frac{1}{2}$

x= $\frac{7}{2}$ · $\frac{2}{1}$

x=14/2=7

What is the goal in solving an equation?

Lelechka [254]

Your answer is, get the variable by itself.

The goal in solving an equation is to get the variable by itself on one side of the equation and a number on the other side of the equation. To isolate the variable, we must reverse the operations acting on the variable. We do this by performing the inverse of each operation on both sides of the equation.

Substitute $u=\ln x$ , so that $\mathrm du=\dfrac{\mathrm dx}x$ . The integral is then equivalent to

$\displaystyle\int\frac{\mathrm dx}{x\ln^px}=\int\frac{\mathrm du}{u^p}=\begin{cases}\dfrac{u^{p+1}}{p+1}+C&\text{for }p\neq1\\\\\ln|u|+C&\text{for }p=1\end{cases}$

Then transforming back to $x$ gives

$\displaystyle\int\frac{\mathrm dx}{x\ln^px}=\begin{cases}\dfrac{\ln^{p+1}x}{p+1}+C&\text{for }p\neq1\\\\\ln|\ln x|+C&\text{for }p=1\end{cases}$
