Answer:
n is equal to -8
Step-by-step explanation:
In order to solve this, we simply need to add 3 to both sides of the equation.
n - 3 = -11
n - 3 + 3 = -11 + 3
n = -8
Answer:
Step-by-step explanation:
Answer:
Step 1 : Multiple both sides by 2
3x + 2y = 1
4x - 2y = 20
Step 2 : Eliminate 1 variable by adding the equations
7x = 21
Step 3 : Divide both sides by 7 to solve for x
x = 3
Step 4: Substitute the value of x into 3x + 2y = 1
3(3) + 2y = 1
Step 5: Solve for y
2y = 1 - 9
2y = -8
*divide by 2
y = - 4
Solution:
(x,y) = (3, -4)
