Hi, I need help with a math question. Thank you to whoever helps me! :)
When solving a system of 2 equations and 2 unknowns using the substitution method, what is the ideal value of the coefficient of the isolated variable?
well, it sure is handy if it is one because you will have to reduce it to one in the end. ( like 1 x = 15 )
When using the substitution method to solve a system of two equations and two unknowns, the ideal value of the coefficient of the isolated variable is 1 or -1.
To explain further, the substitution method involves solving one equation for one variable and substituting that expression into the other equation. This process will result in an equation with only one variable, which can then be solved to find its value.
To isolate a variable, you need to manipulate the equation to have the form: variable = expression. To do this, you can divide both sides of the equation by the coefficient of the variable, which effectively sets the coefficient to 1.
By setting the coefficient to 1 or -1, you simplify the equation and make it easier to solve. This is because multiplying or dividing by 1 does not change the value of the variable.
