Answer: n=12

First, add 45 to both sides, giving you 60=5n

Then, divide both sides by 5, giving you 12=n

Answer:

n = 12

Step-by-step explanation:

Solve for n:

15 = 5 n - 45

15 = 5 n - 45 is equivalent to 5 n - 45 = 15:

5 n - 45 = 15

Add 45 to both sides:

5 n + (45 - 45) = 45 + 15

45 - 45 = 0:

5 n = 15 + 45

15 + 45 = 60:

5 n = 60

Divide both sides of 5 n = 60 by 5:

(5 n)/5 = 60/5

5/5 = 1:

n = 60/5

The gcd of 60 and 5 is 5, so 60/5 = (5×12)/(5×1) = 5/5×12 = 12:

Answer:  n = 12

Solve 3x+2y=4 4x+3y=7 algebraically
Leona [35]
Step 1. Multiply first equation with -3 and the second one with 2. You'll get:
\left \{ {{-9x-6y=-12} \atop {8x+6y=14}} \right.

Step 2. Add both equations together. You'll get:
-x=2, which gives x = -2

Step 3. Replace x = -2 in the first equation and calculate y.
3(-2)+2y=4\\
y=\frac{4+6}{2}=5

The solution is: x=-2, y=5

Write the equation if the line that passes through (4,5) and has a slope of m=3
andrew11 [14]

Answer:

y = 3x - 7

Step-by-step explanation:

The <em>point-slope formula</em> for a straight line is

y – y₁ = m(x – x₁)

x₁ = 4; y₁ = 5; m = 3     Substitute the values

y – 5 = 3(x - 4)             Remove parentheses

y – 5 = 3x - 12             Add 5 to each side

     y = 3x - 7

The graph is a straight line with a y-intercept at y = -7 and a slope = 12/4 = 3.
