<h3>What is basic algebra ?</h3>

Algebra is a branch of mathematics that facilitates the description of problems or situations into mathematical statements. It involves variables like x, y, and z as well as mathematical operations like addition, subtraction, multiplication, and division to generate a valid mathematical statement. All branches of mathematics, such as coordinate geometry, calculus, and trigonometry, employ algebra. An elementary algebraic formula is 2x + 4 = 8. Algebraic expressions serve as the mathematical statement when operations on variables and constants, such as addition, subtraction, multiplication, division, etc., are done.

42=-7(z-3) what does a equals?​
Blizzard [7]

Answer:

42=7(z-3)

We simplify the equation to the form, which is simple to understand  

42=7(z-3)

Reorder the terms in parentheses

42=+(+7z-21)

Remove unnecessary parentheses

+42=+7z-21

We move all terms containing z to the left and all other terms to the right.  

-7z=-21-42

We simplify left and right side of the equation.  

-7z=-63

We divide both sides of the equation by -07 to get z.  

z=9
