If m=10x + 4 and m=5x-4 find m

Since m = 10x + 4 and m = 5x - 4, it is safe to say:

10x + 4 = 5x - 4

Both equations equal to m, thus, the two equations are equal.

Isolating x, we get:

10x - 5x = - 4 - 4

5x = - 8

x = - 8/5

Substituting x back into the equations, we get:

m = 5 (-8/5) - 4 = - 8 - 4 = - 12

We can verify this using the first equation:

m = 10 (-8/5) + 4 = - 16 + 4 = - 12

Thus, m = - 12
