Answer: The correr solution is [tex]x=\frac{17}{34}[/tex]
Step-by-step explanation:
Since the steps in Lin's solution are not shown, we are not able to find her erros. However, we can solve it step by step and find the correct result:
[tex]8(x-3)+7=2x(4-17)[/tex]
Firstly, in the left part of the equation we have to multiply [tex]8[/tex] by the numbers inside the parenthesis; and in the right side we have to solve first what is inside the parenthesis:
[tex]8x-24+7=2x(-13)[/tex]
Adding similar terms in the left side and multiplying [tex]2x[/tex] by the number inside the parenthesis in the right side:
[tex]8x-17=-26 x[/tex]
Isolating [tex]x[/tex]:
[tex]x=\frac{17}{34}[/tex] This is the correct solution
