Question

If m1 = 10x + 4 and m2 = 5x - 4, find m2.

Answer 1

8/5

Explanation:

First you set both equations equal to eachother.10x+4=5x-4 Then you solve. First by subtracting 4 from both sides. You get 10x=5x-8. Then you subtract 5x=-8. Divide by five on both sides and you get -8/-5, which is 8/5

Answer 2

-12

Explanation:

Since m1 = 10x + 4 and m2 = 5x - 4 then we can write it as:

10x+4=5x-4

Combine the like terms:

10x-5x=-4-4

5x=-8

Divide both sides by 5

5x= -8/5

x=-8/5

Now substitute the value of x in 5x-4

= 5(-8/5) - 4

= -8-4

= -12

Thus m2 = -12....
