For this case, the first thing we must do is find the multiples of the coefficients.
We have then:
We observe that the biggest common factor is given by 7.
Therefore, by rewriting the expression we have:
[tex]42x-56y = 7 (6x-8y)[/tex]
Answer:
An equivalent expression is given by:
[tex]7 (6x-8y)[/tex]
