Question

Y-20 = 0.75(x-4) solve for y

Answer 1

Transforming the expression.

y - 20 = 0.75(x - 4) |add 20 to both sides

y = 0.75(x - 4) + 20

we can simplified equation:

use the distributive property: a(b + c) = ab + ac

y = 0.75x - 0.75 · 4 + 20

y = 0.75x - 3 + 20

y = 0.75x + 17

Answer 2

y = 0.75x + 17

Explanation:

y - 20 = 0.75(x-4)

y - 20 = 0.75(x) + 0.75(-4)

y - 20 = 0.75x -3

y = 0.75x -3 + 20

y = 0.75x + 17
