Question

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

−7x + 25 = 48
Step 1: −7x + 25 − 25 = 48 − 25
Step 2: −7x = 23
Step 3: negative seven times x over seven = twenty-three over seven
Step 4: x = twenty-three over seven

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! :)
