Solve for X and y using both equations the point you get will be the point they cross eachother -x-y=1 y=x+3 -x-(x+3)=1 -x-x-3=1 -2x-3=1 +3 both sides -2x=4 ÷-2 both sides x=-2 solve for y y=-2+3 y=1 (-2,1)
Let's solve for x. x + 4 y = ( 14 ) ( 3 ) x + 7 y Step 1: Add -42x to both sides. x + 4 y + − 42 x = 42 x + 7 y + − 42 x − 41 x + 4 y = 7 y Step 2: Add -4y to both sides. − 41 x + 4 y + − 4 y = 7 y + − 4 y − 41 x = 3 y Step 3: Divide both sides by -41. − 41 x − 41 = 3 y − 41 x = − 3 41 y Answer: x = − 3 41 y
