The right side of the equation can be rewritten in terms of p as 4p (4p = 4(x^2 +6) = 4x^2 +24)

Now you have (x^2 +6)^2 - 21 = 4p

Replace (x^2 +6) with p

p^2 - 21 = 4p

Subtract 4p from each side:

p^2 - 21 -4p = 0

Rewrite the expression to get p^2 - 4p -21 = 0

Answer:

Step-by-step explanation:

We are told that n = 3m + 6. Substitutte 3m + 6 for n in the second equation, obtaining:

(3m + 6) - 2m = 2, or 3m + 6 - 2m = 2.

Combining like terms yields

m = -4.

Knowing that m = -4 allows us to calculate n. Use the first equation, n = 3m + 6, for this purpose: n = 3(2) + 6 = 12.

Thus, the solution is (2, 12).

3. Solve using substitution. x - y = 4 3x - 2y = -5

Vedmedyk [2.9K]

Given:

The system of linear equations are $x-y=4$ and $3x-2y=-5$

We need to determine the solution to the system of equations using substitution method.

Solution:

The solution can be determined using the substitution method.

Let us substitute $x=4+y$ in the equation $3x-2y=-5$

Thus, we have;

$3(4+y)-2y=-5$

$12+3y-2y=-5$

$12+y=-5$

$y=-17$

Thus, the value of y is -17.

Substituting $y=-17$ in the equation $x-y=4$ , we get;

$x+17=4$

$x=-13$

Thus, the value of x is -13.

Hence, the solution to the system of equations is (-13,-17)
