Jordan solved the equation โˆ’7x + 25 = 48; his work is shown below. Identify the error and where it was made. โˆ’7x + 25 = 48
Step 1: โˆ’7x + 25 โˆ’ 25 = 48 โˆ’ 25
Step 2: โˆ’7x = 23
Step 3: negative seven times x over seven = twenty-three over seven
Step 4: x = twenty-three over seven

Step 1: He should have added 25 to each side.
Step 1: He should have divided both sides by โˆ’7.
