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

Answer:

3³/⁷

Step-by-step explanation:

-7x+26=48

-7x= 48-25

-7x=23

Then he should send the seven to other side

but the minus symbol remains the same

x=23/7 =3³/⁷

which is in mixed fraction

hence I conclude that Jordan did not do any mistake.
