Solve the simultaneous equations 2x + 3y =10?

2x + 3y = 104x - y = -1what is x and y x= y= or:2x + 3y = 104x - y = -1what is x and y x= y=or:2x + 3y = 104x - y = -1

2x + 3y = 10
4x - y = -1

what is x and y x= y=

or:2x + 3y = 104x - y = -1what is x and y x= y=

or:2x + 3y = 104x - y = -1You have two lines. They look like this:www.wolframalpha.com/input/?i=plot+2x+%2B+3y+%3D+10,+4x+-+y+%3D+-1Where they cross, the values of x and y satisfy both equations simultaneously, so it is called a simultaneous system. There are two ways to find that point. Substitution is when you solve one equation for one variable and substitute that into the other equation.4x - y = -14x + 1 = y Substituting:2x + 3(4x + 1) = 102x + 12x + 3 = 1014x = 7x = 1/2Put that into either equation to find y.2(1/2) + 3y = 101 + 3y = 103y = 9y = 3Elimination is when you add the equations in a way to eliminate one variable. Otherwise the process is the same.2x + 3y = 1012x - 3y = -3------------------ ADD14x .... = 7
