Assuming the equation is 2x^2+8=x^2-16
X= -4

Explanation:
(2x^2+8x)-(x^2-16)=0
You factor by splitting the middle term which gives you (x+4)^2=0
You then want to solve the single variable
(x+4)^2 represents a product of 2 terms which is equal to zero and since all these terms are equal to each other the equation should be x+4=0
Subtract 4 from both sides, you get x = -4

Solve the system of linear equations using the
MArishka [77]

Answer:

no solution

Step-by-step explanation:

y = -2x + 3

6x + 3y = -3

the substitution method means you plug one equation into the next, because the first equation gives us a solution for y we can go ahead and plug that into y of the second equation

6x + 3(-2x + 3) = -3

6x - 6x + 9 = -3

9 = -3

which is false meaning that there are no solutions and the lines don't touch at any point

What’s the solution of x+y=29 and y=4x-11
tia_tia [17]

Answer:

x = 8

y = 21

Step-by-step explanation:

y = 4x − 11

x + y = 29

Solve for x:

x + y = 29

x + 4x − 11 = 29

5x − 11 = 29

5x = 40

x = 8

Solve for y:

y = 4x − 11

y = 4 × 8 − 11

y = 21
