5 ( x − 3 ) + 2 = 7
( 5 ∗ x ) + ( 5 ∗ − 3 ) + 2 = 7
5 x − 15 + 2 = 7
5 x − 13 = 7
5 x − 13 + 13 = 7 + 13
5 x = 20
5 5 x = 5 20
x = 4
To solve the equation 5 ( x − 3 ) + 2 = 7 , first distribute the 5 and combine like terms. Next, isolate the variable by adding and dividing appropriately, resulting in x = 4 . Finally, verify the solution by substituting back into the original equation.
