Find the value of x that will make l and m 7x-7, 4x+14

ohaa [14]

Answer:
x = 7

Explanation:
We are given that:
l = 7x - 7
m = 4x + 14

We want to have:
l = m

Therefore, we will simply equate the two equations and solve for x as follows:
7x - 7 = 4x + 14
7x - 7 - 4x = 4x + 14 - 4x
3x - 7 = 14
3x - 7 + 7 = 14 + 7
3x = 21
x = $\frac{21}{3}$
x = 7

Hope this helps :)

What is the least common denominator of the expressions? x + 1/4x and 3(X + 1)/2x2

chubhunter [2.5K]

Answer:

LCD = 4 x^2

Step-by-step explanation:

The least common denominator : LCD

(x + 1) / 4x and (3(x + 1)) / 2x^2

factor 4x : 2, 2, x

factor 2x^2 : 2, x, x^2

take highest powers 2^2 and x^2

LCD is 4*x^2
