Let x = Initial Price

If we increase x by 5%, we are adding 0.05x

Therefore, the new price = x + 0.05x = 1.05x

If the ticket has increased by £2.30, £2.30 is 5% of the initial price, or 0.05x

0.05x = 2.30

x = 2.30/0.05

x = 46

Therefore, the price of the ticket before the increase was £46

You can also check this backwards by doing 46*0.05 = 2.30

Solve and graph the solutions of the equation 2|x-2|-12=0

defon

2|x-2|-12=0

Rearrange variables to the left side of the question

2|x-2|=12

Dividing both sides of the equation by the coefficent of variables

|x-2|=12/2

Reduce the fraction

|x-2|=6

Split into two variables

x-2=6 or x-2=-6

Rearrange variables to the left side of the equation

x=6+2

x=8 or x=-4

when x=8

LHS=2|8-2|-12=0

RHS=0

LHS=RHS

x=8 is valid

A variable in mathematics is an alphabet or phrase that stands in for an unknowable amount, unknowable value, or unknowable number. Particularly in the case of algebraic expressions or algebra, the variables are utilised. As an illustration, the linear equation x+9=4 has the variables x and 9 as constants.

A variable is a letter or symbol that stands in for any individual integer in a group of two or more. A constant is a letter or symbol that stands for a single particular number, whether it is known or unknown.

In mathematics, variables serve as stand-ins for unknowable numbers. Variables can be utilized in formulae, equations, and expressions in mathematics. When it's necessary to find the optimum solution, variables are frequently employed.
