Find the greatest common factor of 15 x²y³ and -18 x³yz .

3 x² y¹

Step-by-step explanation:

15 x²y³ =3. 5. x². y³

-18x³yz = -2. 3².x³. y¹. z¹

so, the GCF = 3. x². y¹

Solution given:

15x²y³=3*5*x*x*y*y*y

-18x³yz=-3*2*3*x*x*x*y*z

over here common is

3*x*x*y

so

greatest common factor is 3x²y¹

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
