Jason solved the following equation to find the value for x. –8.5x – 3.5x = –78

x = 6.5

Describe how Jason can check his answer.

Sample

Substitute the value for x into the original equation. Simplify using order of operations. If the statement is true, Jason’s solution for x is correct. If the statement is false, Jason’s solution for x is incorrect.

Step-by-step explanation: (My answer)

1) Subtract 8.5 and 3.5, that equals 12.

2) Multiply 78 and 12, that equals 6.5 .

3) Check your answer.

Multiply 8.5 and 6.5, that equals 55.25. Next, multiply 3.5 and 6.5, that equals 22.75.Finally, you will need to subtract your answers. Subtract both 55.25 and 22.75.

Once you've done that, the answer you should get is 78.

78 is equal to 78, that is your final answer and it is correct.

Convert everything to whatever/24

4/24 + 6/24 + 8/24 = 18/24

simplify that to 3/4

so the answer is 1/4 because you do 1 - 3/4

(1 represents her total weekly allowance, 3/4 is the amount she used, so 1/4 is the amount she has left.)
