How do I solve problems like this? I did it last year, but I don't remember how to do it. Solve for x:

1/2x + 3 = 7

2x + 3 - 4x - 7 = 11

thanks!!

What power can you write to represent the volume of the cube shown? write the power as an expression with a base and an exponent and then find the volume of the cube

Which steps could be part of the process in algebraically solving the system of equations, y+5x=x^2+10 and y=4x-10

Select the correct answer from each drop-down menu. consider the following polynomials equations. 3x^2(x-1) and -3x^3+ 4x^2-2x+1 perform each operation and determine if the result is a polynomial. is the result of a + b a polynomial? yes or no is the result of a - b a polynomial? yes or no is the result of a · b a polynomial? yes or no
