Question

How do you do number 11?

Answer 1

a-c/x-a = m
x-a/a-c = 1/m
x-a = a-c/m
x = a + a-c/m

Answer 2

`(a - c)/(x - a)` = m Multiply both sides by (x - a)
a - c = m (x - a) Use the Distributive Property
a - c = mx - ma Add ma to both sides
a - c + ma = mx Divide both sides by m

`(a - c + ma)/(m)` = x Switch the sides to make it easier to read
x =
`(a - c + ma)/(m)`
