Answer:

$(3,2)$

Step-by-step explanation:

The method of variable substitution is a way of solving a system of equations. It involves solving one equation for a variable and then substituting in the expression that represents the value of the solved variable into the other equation. After doing so, one can solve for the unknown variable and then backsolve for the other variable.

$y=-2x+8\\y=x-1$

In this system, the second equation is already solved for (y), thus one can substitute that expression into the other equation in the system.

$x-1 = -2x + 8$

Now solve using inverse operations,

$x -1 = -2x + 8\\+2x\\\\3x - 1 = 8\\+1\\\\3x =9\\/3\\\\x = 3$

Backsolve to find the value of (y), substitute in the value of (x), and solve for the value of (y).

$y=x - 1\\$

Substitute,

$y=(3)-1$

Solve,

$y=2$

Thus, the answer to this system of equations is the following, $(3,2)$ .

What are the solutions to the equation x - 7/x = 6

bearhunter [10]

The answer is C that is X=7 and X=-1

multiple x through the given equation to get rid of a fraction. It will be

${x}^{2} - 7 = 6x$

After that bring 6X to the LHS of the equation

so that it will look like the general equation that is

${x}^{2} - 6x - 7 = 0$

Use the quadratic formula (or any other approach to find the values of x

You will arrive at

$x = 7. - 1$
