Someone solve this ?

x = 6

Step-by-step explanation:

6(9+x) = 5(3x)

6*9 + 6*x = 5*3x

54 + 6x = 15x

54 = 15x - 6x

54 = 9x

x = 54/9

x = 6

check:

(9+6)/(3*6) = 5/6

15/18 = 5/6

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

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
