Answer:
d) 2
Step-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]
