Answer: x = ± 1.68
Step-by-step explanation:
7x^4 = 56
x^4 = 56/7
x^4 = 8
Let a = x²
(x²)² = 8
(a)² = 8
a = ± √8
Now,
a = -√8
x² = -√8 has no real solution.
Taking +√8
a = √8
x² = √8
x = ± √(√8))
x = ± 1.68
900 because 9 is greater than 5 so it rounds to my answer.
The solution to the given system of equation is (7,-3).
<h3>What is the solution to the given system of equation?</h3>
Given the equations in the question;
2x + 7y = -7 ----- equ 1
-4x - 3y = - 19 ---- equ 2
First, we solve for x in equation 1
2x = -7y - 7
x = -7y/2 - 7/2
Next, replace all occurrence of x with -7y/2 - 7/2 in equation 2
-4x - 3y = - 19
-4(-7y/2 - 7/2) - 3y = - 19
14y + 14 - 3y = -19
14y - 3y = -19 - 14
11y = -33
y = -33/11
y = -3
Plug y = -3 into equation 1 and solve for x
2x + 7y = -7
2x + 7(-3) = -7
2x - 21 = -7
2x = -7 + 21
2x = 14
x = 14/2
x = 7
Therefore, the solution to the given system of equation is (7,-3).
