y=3x+1 y=-2x+3 Make these equal each other: 3x+1=-2x+3 Add 2x to both sides: 3x+2x+1=-2x+2x+3 = 5x+1=3 Subtract 1 from both sides; 5x+1-1=3-1 = 5x=2 Divide 5 from both sides: 5x/5=2/5 X= 2/5 Plug X into one of the equations: y=3(2/5) +1 y=11/5(2.2)
there could be multiple ways to get to a certain number like 1 to 3 could be + 2 or multiplying 3 so you have to check the next numbers to see if it is adding 2 or multiplying 3
