Question

solve the following equations using systematic method (4x-7/2=1/2)
this is too urgent plz ​

Answer 1

Answer:

Rule 1) We can add the same number to both sides of the equation, i.e., if x + 5 = 7, then x + 5 + 2 = 7 + 2.

Rule 2) We can subtract the same number from both sides of the equation, i.e., if x + 5 = 7, then x – 5 – 2 = 7 – 2.

Rule 3) We can multiply both sides of the equation by the same non-zero number, i.e., if \frac{x}{3} = 4, then (\frac{x}{3})(6) = (4)(6). Also, (\frac{x}{3})(3) = (4)(3).

Rule 4) We can divide both sides of the equation by the same non-zero number, i.e., if 3x = 10, then \frac{3x}{3} = \frac{10}{3}. Also, \frac{3x}{5} = \frac{10}{5}.
