12x2 + 7x + 1 = 12x2 + 3x + 4x + 1 = 3x*(4x + 1) + 1*(4x + 1) = (4x + 1)*(3x + 1)
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=3x+8 7x-3x=8+3 4x=11 x=11/4=2.75
Oh, dude, that's like basic math, but sure, I'll help you out. So, 7x + 4x equals 11x. It's like adding up all the x's in the neighborhood and getting 11 of them. Math can be fun, right?

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.
In the expression (4x^3 - 7x^2 \times x^3), the like terms are those that have the same variable raised to the same power. Here, (4x^3) and (-7x^2 \times x^3) can be simplified to (-7x^5). Thus, the like term in this case is (4x^3) and (-7x^5), but they are not like terms since they are raised to different powers. Therefore, there are no like terms in the expression.

4y + 3w + 4x + 9y + 7x - 7w (combine like terms)-4w + 11x + 13y
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
4x-7x = -3
you have to combine like terms so its 4x-824. just simplify it.

To simplify the expression ((7x - 5) - (3x - 2)), first distribute the negative sign: (7x - 5 - 3x + 2). Next, combine like terms: (7x - 3x = 4x) and (-5 + 2 = -3). Thus, the equivalent expression is (4x - 3).

-4x=10 and -7x is 65? -4x=10 therefore 4x is -10, x = -2.5 -7x = 65, 7x = -65, x = -9.26
