<h3>How to solve equations?</h3>
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
In other words, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The expression can be solved as follows:
b / 27 = - 3
cross multiply
b = -3 × 27
b = - 81
42 = v + 35
subtract 35 from both sides of the equations.
42 - 35 = v + 35 - 35
v = 42 - 35
v = 7
- 128 = 4x
divide both sides of the equations by 4
4x / 4 = - 128 / 4
x = - 32
