The solutions to the system of equations are given as follows: (1, -3) and (-4,2).
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
The equations are given as follows:
- (x + 3)² + (y + 2)² = 17.
From the second equation:
y = -2 - x.
Replacing in the first:
(x + 3)² + (y + 2)² = 17.
(x + 3)² + (-2 - x + 2)² = 17
x² + 6x + 9 + x² = 17
2x² + 6x - 8 = 0
2(x² + 3x - 4) = 0
2(x + 4)(x - 1) = 0.
Then the solutions for x are:
The solutions for y are:
- When x = 1, y = -2 - 1 = -3.
- When x = -4, y = -2 -(-4) = 2.
Hence the solutions are:
(1, -3) and (-4,2).

ex = 18 e x = 18 Take the natural logarithm of both sides of the equation to remove the variable from the exponent. ln(ex) = ln(18) ln (e x) = ln (18)
divide the volume of jupiter by the volume of earth
1.43*10^15/ 1.09*10^12
1.43/ 1.06 *10^(15-12) divide the number, subtract the exponent
1.311926606 *10^3
