Combine like terms and use the properties of equality to get the variable on one side of the equal sign and the numbers on the other side.Remember to follow the order of operations. Them multiply -1 times -3x+1 . then add -1 to 2.then add 1 to both sides of the equation then subtract 3x from the both sides of equation and lastly diveide both sides of the equation by -5.. So the answer is

x = -2/5
