What’s the equation of N -32 equals 15

N = 47

Step-by-step explanation:

Simplifying

N + -32 = 15

Reorder the terms:

-32 + N = 15

Solving

-32 + N = 15

Solving for variable 'N'.

Move all terms containing N to the left, all other terms to the right.

Add '32' to each side of the equation.

-32 + 32 + N = 15 + 32

Combine like terms: -32 + 32 = 0

0 + N = 15 + 32

N = 15 + 32

Combine like terms: 15 + 32 = 47

N = 47

Simplifying

N = 47

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

answer:   2 multiplied by x =24
