Step-by-step explanation:

C=b/a

c=kb/a

where as k is the constant

c=kb/a

we substitute

33=22k/6

crossed multiply

33*6= 22k

198=22k

we divide both sides by 22

198/22=22k/22

K=9

Solve the simultaneous equation <br> 2x-5y=9<br> 3x+4y=2
Dmitriy789 [7]

Answer/Step-by-step explanation:

2x-5y=9

Add 5y  to both sides of the equation.

2x=9+5y

Divide each term by 2 and simplify.

Divide each term in 2x=9+5y by 2

\frac{2x}{2} =\frac{9}{2} +\frac{5y}{2}

Cancel the common factor of 2.

Divide x by 1.

x=\frac{9}{2} +\frac{5y}{2}

y=\frac{-9}{5} +\frac{2x}{5}

----------------------------------------------------------------------------------------------------------------

3x+4y=2

Add 4y to both sides of the equation

3x=2+4y

Divide each term by 3 and simplify.

Divide each term in 3x=2+4y by 3.

\frac{3x}{3} =\frac{2}{3} +\frac{4y}{3}

Cancel the common factor of 3.

Divide x by 1.

x=\frac{2}{3} +\frac{4y}{3}

y=\frac{-1}{2} +\frac{3x}{4}
