Answer:

Multiply by 2

Step-by-step explanation:

If we multiply 2x-6y=26 by 2, we get 4x-12y=52 and the x's cancel out, making it easier to solve for y, using the elimination process.

Hope this makes sense!

Apply the distributive property to create an equivalent expression.

Bumek [7]

Given:

The expression is

$(1-2g+4h)\cdot 5$

To find:

The equivalent expression.

Solution:

Distributive property of multiplication over addition is

$a(b+c)=ab+ac$

Where, a, b and c are real numbers.

We have,

$(1-2g+4h)\cdot 5$

Using distributive property, we get

$=(1)\cdot 5+(-2g)\cdot 5+(4h)\cdot 5$

$=5-10g+20h$

Therefore, the expression $5-10g+20h$ is equivalent to the given expression.

X^lg(x)=100^x find x

Wittaler [7]

$x^lg(x)=100^x$

$X^lg(x)=100^x:x$ $|Solve \ for \ x|$

$|Use \ logarithms \ of \ both \ sides \ of \ the \ base \ 10|

$

$lg (x ^ lg (x)) = lg (100x)

$

$lg ^ 2 (x) = 2 + lgx$

$lg 2 ^ x-lg x -2 = 0$

$lg x = 2 x = 100$

$lg x = -1 x = \dfrac{1}{10} = 0.1$
