Answer:

by what?

Step-by-step explanation:

what do we need to divide by

To solve [tex]\rm 5(2\times 4) = 15[/tex], first divide each side by then,[tex]\rm x=\dfrac{-1}2[/tex] will be the value of x

Given Equation :  [tex]=\rm 5(2\times 4) = 15[/tex]

What is Linear Equation method?t

To solve linear equations that means finding the value of variables that will be given in the linear form of equations. A linear equation is also a combination of an algebraic expression with degree 1 .

Now,we will solve this by simply Linear Equation method,

      [tex]\rm 10x+20=15\\\\10x=15-20\\\\10x= -5\\\\x=-1/2[/tex]

Therefore the value of x will be [tex]\rm x=\dfrac{-1}2[/tex]
