Question

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

Answer 1

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 :)
