Step-by-step explanation:

Move numbers with (x) on one side turning it into (-)

x = 6/5

Step-by-step explanation:

Rearrange unknown terms to the left side of the equation:

 7x − 2x = −1 + 7

Combine like terms:

 5x = −1 + 7

Calculate the sum or difference:

 5x = 6

Divide both sides of the equation by the coefficient of variable: 

x = 6 ÷ 5

Calculate the product or quotient: 

x = 1.2

Express the number in fractions:

 x= 6/5

Answer:

x = 6/5
