Answer:d) 2Step-by-step explanation: 5x + 3 = 7x – 1 now collect like terms 3 + 1 = 7x – 5x every time you move something it changes signs 4 = 2x anything multiplied is divided on the other side and vice versa 4/2 = x 2 = x
Step-by-step explanation:[tex]5x + 3 = 7x - 1[/tex]First, let's move everything with an [tex]x[/tex] to the left-hand side of the equation, and everything else to the right-hand side:[tex]5x - 7x = -1 - 3[/tex][tex]-2x = -4[/tex]Now, let's divide both sides by [tex]-2[/tex] to isolate the [tex]x[/tex] on the left-hand side of the equation:[tex]\frac{-2x}{-2} = \frac{-4}{-2}[/tex][tex]x = 2[/tex]
