1 answer:

8 0

X=5 and y =2.
Here's how you do it.
Multiply the first equation by -3, and the second one by 1.
add the equations to eliminate x.
then solve for y by dividing both sides by -5, which gives us 2.
to solve for x subsitute 2 in for y.

Which equation is equivalent to log Subscript 3 Baseline (x 5) = 2?.

grin007 [14]

The equivalent equation is x - 4 = 0.

<h2>Linear system</h2>

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

<h3>Simplification</h3>

Simplification is to make something easier to do or understand and to make something less complicated.

Given

The expression is $\rm log_3(x + 5) = 2$ .

The equivalent equation.

<h3>How to find the equivalent equation.</h3>

The expression is $\rm log_3(x + 5) = 2$ .

On simplifying. we get

$\begin{aligned} \rm log_3(x + 5) &= 2\\x + 5 &= 3^2\\x + 5 &= 9 \\x &= 9 - 5\\x &= 4\\x - 4 &= 0\\\end{aligned}$

The equivalent equation is x - 4 = 0.
