An easy way to check your answers: put your answer (1) in place of your variable (x).
So, does 3x1 + 7 = 2x1?
The left hand side equals 10, but the left hand side equals 2.
1 doesn't make the equation work, so it is not a solution.
To solve the equation (or any linear equation of one variable), get the x on one side and all the other numbers on the other side by doing the same arithmetic (+,-,x,/) to both sides.
3x + 7 = 2x Subtract 2x from each side.
x + 7 = 0 Subtract 7 from each side.
x = -7
So the solution to 3x + 7 = 2x is x = -7.
3x + 7 = 2x
Subtract '2x' from both sides
Hence
x + 7 = 0
Subtract '7' from both sides.
x = -7
The answer is '-7' Minus seven'. NOT '1'
