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: 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 β7. Step 3: He should have divided both sides by β7. Step 3: He should have multiplied both sides by β7.
