i 'll do it in blue . so right now it 's in standard form . let 's put it in slope-intercept form .
what is the point of standard form ?
we 're told to solve and graph the solution for the system of equations right here . and the first thing that jumps out at me , is that we might be able to eliminate one of the variables . and if we just focus on the x , we have a 4x here and we have a 2x right here . if we were to just add them right now , we would ge...
i 'll do it in blue . so right now it 's in standard form . let 's put it in slope-intercept form . so we have 4x minus 2y is equal to 5 .
instead of changing 4x - 2y = 5 to slope-intercept form in order to graph it , how ( if you even can ) would you graph the equation while keeping it in standard form ?

anything i do to the left-hand side of the equation i have to do to every term , and i have to do to both sides of the equation . so the second equation becomes negative 4x -- that 's negative 2 times 2x -- plus -- we have negative 2 times negative y -- which is plus 2y is equal to 2.5 times negative 2 , is equal to ne...
if -3x-6y=-63 , how do you know if the `` 6y '' is negative ?

let 's put it in slope-intercept form . so we have 4x minus 2y is equal to 5 . let 's subtract 4x from both sides .
what is the solution of 4x+y=57 and 7x-2y=21 ?

now we can divide both sides by negative 2 . and we are left with y is equal to positive 2x , right , that 's positive 2x , minus 2.5 . so let 's graph that .
how do i solve : 8x-7y=21 2x=3y+4 using addition/elimination ?

any point on this line , which is both of those lines , will satisfy both of these equations . you give me an arbitrary y , solve for x in the top equation , that x and y will also satisfy the bottom equation . so this actually has an infinite number of solutions .
how do i solve : x+3y-z=10 2x+5y+4z=57 3x-y+2z=15 using elimination ?
