2x + 3 = 3x - 4
7 = 5x
1.2 = x

Not quite right, I'm afraid:
the correct answer is x = 7.
Here's one way to find it:
2x + 3 = 3x - 4.
Then,
2x + 3 - 3x + 4 = -x + 7 = 0, and
x = 7,
which is the answer we sought.
Checking, we try substituting 7 for x,
in the original equation:
Does 2x + 3 = 3x - 4, when x = 7?
Let's try:
2(7) + 3 = 17, and
3(7) - 4 = 17.
Yes, it does;
thus assuring us that our answer is correct.

2x plus x equals?
3x
3x-y equals 3 y equals 2x plus 2?
3x - y = 3y = 2x + 2Put the value of y in the 1st equation:3x - y = 3 it will be -->3x - ( 2x + 2 ) = 33x - 2x - 2 = 3x - 2 = 3X = 5Put the value of X in the 2nd equation so as to find the value of Y :y = 2x + 2y = 2(5) + 2y = 10 + 2Y = 12
3x plus 5 divided by 4 equals negative 2x plus 15?
Presumably, this is an equation in finding the value of x 3x+5/4 = -2x+15 3x+1.25 = -2x+15 3x+2x = 15-1.25 5x = 13.75 x = 2.75
