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 step 1: he should have added 25 to each side. step 1: he should have divided both sides by −7. step 3: he should have divided both sides by −7. step 3: he should have multiplied both sides by −7.
