Let's solve your equation step-by-step. 3 x + 1 = 3 x Step 1: Subtract 3x from both sides. 3 x + 1 − 3 x = 3 x − 3 x 1 = 0 Step 2: Subtract 1 from both sides. 1 − 1 = 0 − 1 0 = − 1
D there is always a 1 infront of a variable but since x2 has the largest degree it gives it priority over the others so what ever numbe in front of it is the leading coefficient
