Answer 2

Given:

3x divides by 5 =15

To Find:

solve each of the following equations and verify the answer in each case ​

Solution:

An equation is any mathematical statement that has an equal to sign, and a linear equation is an equation in which there is a variable whose value is unknown or is indicating the location on the x-y plane,

For the given statement 3x divides by 5 is 15 can be expressed as,

$\frac{3x}{5} =15$

Now multiply both sides by 5 we have,

$3x=75$

Now divide both sides by 3 we have,

$x=25$

So we have a value for x and we can check the same by putting the value in the main equation that is,

$\frac{3x}{5} =15\\\frac{3*25}{5} =15\\3*5=15\\15=15$

Hence, verified for x=25.
