To solve this equation, repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the equal sign and the answer on the other.

3x - 7 = \( \frac{x}{1} \)
1 x (3x - 7) = x
(1 x 3x) + (1 x -7) = x
3x - 7 = x
3x - 7 - x = 0
3x - x = 7
2x = 7
x = \( \frac{7}{2} \)
x = 3\(\frac{1}{2}\)

To multiply monomials, multiply the coefficients (the numbers that come before the variables) of each term, add the exponents of like variables, and multiply the different variables together.

(7a)(5ab) + (8a²)(6b)
(7 x 5)(a x a x b) + (8 x 6)(a² x b)
(35)(a¹⁺¹ x b) + (48)(a²b)
35a²b + 48a²b
83a²b

The entire length of this line is represented by AD which is AB + BD:

AD = AB + BD

A cylinder is a solid figure with straight parallel sides and a circular or oval cross section with a radius (r) and a height (h). The volume of a cylinder is π r²h and the surface area is 2(π r²) + 2π rh.

To multiply monomials, multiply the coefficients (the numbers that come before the variables) of each term, add the exponents of like variables, and multiply the different variables together.

6a x 2b = (6 x 2) (a x b) = 12ab
