Answer:

111111 $\times$ 1111110 is the simple expression.

Step-by-step explanation:

The expression to be solved:

$\dfrac{6,666,666\times666,666 }{1+2+3+4+5+6+5+4+3+2+1} - \dfrac{777,777\times777,777}{1+2+3+4+5+6+7+6+5+4+3+2+1}$

First of all, let us solve the first term:

$\dfrac{6,666,666\times666,666 }{1+2+3+4+5+6+5+4+3+2+1}\\\Rightarrow \dfrac{6666666\times666666 }{36}\\\Rightarrow \dfrac{6666666\times666666 }{6\times 6}\\\Rightarrow 1111111\times 111111$

Now, the right term:

$\dfrac{777777\times777777}{1+2+3+4+5+6+7+6+5+4+3+2+1}\\\Rightarrow \dfrac{777777\times777777}{49}\\\Rightarrow \dfrac{777777\times777777}{7 \times 7}\\\Rightarrow 111111 \times 111111$

So, the expression to be solved becomes:

$1111111\times 111111-111111\times 111111\\\Rightarrow 111111(1111111-1)\\\Rightarrow 111111\times 1111110$

Substitute the known value of x into y=4x+20. Then solve for y entering the equation in simplest form

scoray [572]

Answer:

$y=24,$ when $x=1$ .

Step-by-step explanation:

Given: $y=4x+20$

To find: Value of $y$ , substituting the known value of $x$

We have,

$y=4x+20 ...(i)$

Putting $x=1$ in equation $(i)$ , we get

$y=4(1)+20$

$\implies y=4+20$

$\implies y=24$

Hence, the value of $y$ is $24$ , when the value of $x$ is $1$ .
