Answer:

2(3x−4)+1=5

Subtract 1 from both sides

2(3x−4)=4

Divide both sides by 2

3x−4=2

Add 4 to both sides

3x=6

Divide both sides by 3

x=2

Another method:

2(3x−4)+1=5

First multiply out (expand) the brackets

6x−8+1=5

Collect together like terms

6x−7=5

Add 7 to both sides

6x=12

Divide both sides by 6

x=2

Step-by-step explanation: A linear equation is an equation in which each term is either a constant or the product of a constant times the first power of a variable. In simple terms it is a mathematical sentence in which you can see only one letter (which might appear more than once) but there will be no powers (squared, cubed etc). Here is an example of a simple linear equation
