Question

Value of X : 3x-5=25

Answer 1

3x-5=25

or,3x=25+5(transposing 5 to RHS)

or,3x=30(dividing both sides by 3)

or,x=30/3

or,x=10(solution)

it is a type of linear equation in one variable

how to do a linear equation in one variable:-

The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations.
