Question

Упростите выражение( 3x+z)/(5x-2z)-(2/3)

Answer 1

(3x+z)/(5x-2z) -2/3=(9x+3z-10x+4z)/3(5x-2z)=(7z-x)/3(5x-2z)

Answer 2

$\frac{3x+z}{5x-2z} - \frac{2}{3} = \frac{3(3x+z)-2(5x-2z)}{3(5x-2z)} = \frac{9x+3z-10x+4z}{15x-6z} = \\ = \frac{7z-x}{15x-6z}$

Answer 3

I can help you with math problems. To simplify the expression, we need to find a common denominator and subtract the fractions. The common denominator is 15x - 6z. We get:

$$\frac{3x+z}{5x-2z}-\frac{2}{3}=\frac{9x+3z-10x+4z}{15x-6z}=\frac{-x+7z}{15x-6z}$$
