Answer:
X= 22/7
Step-by-step explanation:
7+X/3 = 2x - 5
7 + x = 3( 2x - 5) [ cross multiplication]
7 + X = 6x - 15
Move variable to LHS and change its sign
X - 6x + 7 = -15
Move constant to R.H.S and change its sign
X - 6x = -15 - 7
Collect like terms
-5x = -15 - 7
Calculate the difference
-5x = -22
The difference sign(-) will be cancelled in both sides
5x = 22
divide both sides of the equation by 5
5x/5 = 22/5
calculate
X = 22/5
Hope this helps..
Good luck on your assignment...
