4x-7x = -3
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.
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.
7x = 4x - 93x = -9x = -3
-3x=-21+4x-3x-4x=-21+4x-4x-7x=-217x=217x/7=21/7x=3

-4x=10 and -7x is 65? -4x=10 therefore 4x is -10, x = -2.5 -7x = 65, 7x = -65, x = -9.26
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.
7x = 4x - 93x = -9x = -3
As there are no parentheses then the expression stated can be simplified as follows :- 7x - 4x - 9 = 3x - 9 If the parentheses were placed (7x - 4x) - 9 then the result would be the same. If the parentheses were placed 7x - (4x - 9) = 7x - 4x + 9 = 3x + 9.
4x+9 = 7x+3 4x-7x = 3-9 -3x = -6 x = 2

-3x=-21+4x-3x-4x=-21+4x-4x-7x=-217x=217x/7=21/7x=3
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
