Question

Solve the following equation: 45-3x=18
I tried x=9 but it said it was wrong

Answer 1

Answer: x =
`(15)/(7)`

Explanation:

To solve, we will isolate the variable by using reverse operations. You commented the proper equation is 45 - 3x = 18x

Given:

45 - 3x = 18x

Add 3x to both sides of the equation:

45 = 21x

Divide both sides of the equation by 21:

x =
`(15)/(7)`
