10x + 7 + 3x = 13x + 7
(-3x - 1)(3x - 7)
38*4 + 3 + 7 - 3x = 162 - 3x
The answer to the expression 3x + 9 depends on the value of x. If x is a specific number, you would first multiply 3 by that number, then add 9 to the result. For example, if x = 2, the answer would be 3(2) + 9 = 6 + 9 = 15. However, if x is a variable, the expression 3x + 9 remains as is and cannot be simplified further without knowing the specific value of x.
3x+7=4x 7=4x-3x 7=x
3x plus 2y can be expressed mathematically as (3x + 2y).
5x+7
13x + 7
if 3x+7 = 3 then 3x = 3-7 3x = -4 then, x = -4/3
4x plus 7 plus 3x equals 19 plus xx = 2
d/dx 2x2+3x+7=4x+3
