Question

Jordan solved the equation −7x + 25 = 48; his work is shown below. Identify the error and where it was made.

Answer 1

You have to divide the negtive seven over to the other side

Answer 2

She did everything correct in step 1 and 2 
Until step 3 she took a wrong turn. 
She wrote seven times x over seven = twenty-three over 7

When she should have wrote..
negative seven times x over negative seven = twenty-three over negative seven

So her answer was 
23/7 
while it should have been a negative. ->   -23/7 

Good Luck! :)
