Jordan solved the equation β7x + 25 = 48; his work is shown below. identify the error and where it was made.
β7x + 25 = 48
step 1: β7x + 25 β 25 = 48 β 25
step 2: β7x = 23
step 3: -7x/7 = 23/7
step 4: x = 23/7
step 1: he should have added 25 to each side.
step 1: he should have divided both sides by β7.
step 3: he should have divided both sides by β7.
step 3: he should have multiplied both sides by β7.
