Need help on this question

<u>Given:</u>

The two equations are $2x-5y=-7$ and $5x-3y=11$

We need to solve the equations using elimination method.

<u>Elimination method:</u>

Let us multiply the equation $2x-5y=-7$ by 5, we get;

$10x-25y=-35$ ---------(1)

Now, multiplying the equation $5x-3y=11$ by -2, we get;

$-10x+6y=-22$ --------(2)

Adding equations (1) and (2), we have;

$\ \ \ 10x-25y=-35\\-10x+\ \ 6y=-22\\---------\\-19y=-57$

$y=3$

Thus, the value of y is 3.

Substituting $y=3$ in the equation $2x-5y=-7$ , we have;

$2x-5(3)=-7$

$2x-15=-7$

$2x=8$

$x=4$

Thus, the value of x is 4.

Hence, the solution of the system of equations is (4,3)

Therefore, Option A is the correct answer.

If the product of six tenths and three tenths is subtracted from the sum of two tenths and four tenths, what

MakcuM [25]

Answer:

$-\frac{1}{200}$

Step-by-step explanation:

$\frac{6}{10}$ × $\frac{3}{10}$ - $\frac{2}{10}$ + $\frac{4}{10}$

$\frac{6}{10}$ × $\frac{3}{10}$ = $\frac{18}{100}$

$\frac{18}{100}$ - $\frac{2}{10}$ = $-\frac{1}{50}$

$-\frac{1}{50}$ + $\frac{4}{10}$ = $\frac{1}{200}$
