Yes; that's because the powers of the variables are the same .. -7x has a variable x with power 1 (x^1), and so is 4x.
4x and -7x are like terms because they are both multiplying x. It While (4 +- 7)x = -3x

How do you Factorise this 12x square 7x plus 1?
12x2 + 7x + 1 = 12x2 + 3x + 4x + 1 = 3x*(4x + 1) + 1*(4x + 1) = (4x + 1)*(3x + 1)
How do you solve equations with like terms on one side of the equal sign?
You move one of the like terms to the other side using algebraic operations. For instance... 3x + 5y = 7x + 3 ... and you want to solve for x ... ... first, subtract 3x from both sides ... 3x - 3x + 5y = 7x - 3x + 3 5y = 4x + 3 ... do I need to explain further???
7x-3 equals 3x plus 8?
7x-3=3x+8 7x-3x=8+3 4x=11 x=11/4=2.75

What is 7x - 4x plus x - 15?
To do this equation, you collect like terms. 7x-4x+x-15 is your original equation, you have 3 terms with "'x'" in them, and they are 7x, -4x, and x. 7x + (-4x) +x simplifies to 4x, because 7-4 = 3 + 1 = 4 (the x is really 1x....). After this, you get 4x-15, which is as simplified as this equation can be.
What is 4y plus 3w plus 4x plus 9y plus 7x-7w?
4y + 3w + 4x + 9y + 7x - 7w (combine like terms)-4w + 11x + 13y
How do you slove 3x plus 1 plus 4x-5 equals 31?
combine like terms. 3x+1+4x-5=31 3x+4x=7x 7x+1-5=31 1-5=-4 7x-4=31 then solve it 7x=35 x=5
How do you solve this equation 7x-3x-824?

What is the answer to -4x 10or-7x 65?
-4x=10 and -7x is 65? -4x=10 therefore 4x is -10, x = -2.5 -7x = 65, 7x = -65, x = -9.26
Simplify 5x2 - 7x - 2x - x2?
Separate and simplify the common terms. 5x^2 - X^2 = 4x^2 -7x - 2x = -9x Now put these terms back together 4x^2 - 9x Or if simplified further, you get: x(4x-9)
What is 7x equals 4x-9?
7x = 4x - 93x = -9x = -3
