4 x − 11 = 21 4 x = 21 + 11 4 x = 32 / : 4 x = 8 32 x = 4
4x - 11 = 21 4x = 21 + 11 4x = 32 x = 32 divided by 4 x = 8 Hope that helps! :)
To solve 4 x − 11 = 21 , first add 11 to both sides to get 4 x = 32 and then divide by 4, resulting in x = 8 . Verification by substituting back into the original equation shows the solution is correct.
