Find the age of the father. 16. A boat takes 4 hours to go 44 km downstream and it can go 20 km upstream at the same time. WebThe 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. Sort by: Top Voted Questions Tips & Thanks
WebThe system of linear equations in two variables is the set of equations that contain only two variables. For example, 2x + 3y = 4; 3x + 5y = 12 are the system of equations in two variables.
