<span>4x + 3y = 16
7x + 6y = 31

Note what happens if we mult. the first eqn. by -2:

-8x - 6y = -32

Combining this with the 2nd equation eliminates the variable y:

</span>-8x - 6y = -32<span>
7x + 6y = 31
--------------------
-x = -1, or x = 1. Sub 1 for x in either of the 2 given eqns to find y:

For example: 4(1) + 3y = 16, so 36 = 12, and y = 3. Sol'n is (1,3).</span>

Answer:

The new ratio is $\frac{7}{3}$ ⇒ (D)

Step-by-step explanation:

<em>The given information is</em>

6 parts of yellow paint with 3 parts of blue paints to make green paint
The yellow paint adds by 1 part

We need to find the ratio of yellow to blue

<em>Let us find the correct answer</em>

∵ The yellow = 6 parts

∵ The yellow adds by 1 part

∴ The yellow = 6 parts + 1 parts = 7 parts

∵ The blue = 3 parts

∵ The ratio of yellow to blue = $\frac{yellow}{blue}$

∴ The ratio of yellow to blue = $\frac{7}{3}$

The new ratio is $\frac{7}{3}$
