Combine like terms by subtracting x from both sides.
x + 4 = 2x
4 = 2x - x
4 = x
(On one side, x-x cancelled out, and on the other side, the 2x-x works like normal subtraction so you are left with x. Therefore x is 4)

Answer: -130, - 129, - 128
Step-by-step explanation:
x + x+1 + x+2 = - 387
3x + 3 = - 387
3x = - 387 - 3
x = - 390/3
x = - 130
Answer:
The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations.
