Answer:
solve simultaneously
start by labeling them equation 1 and 2 then choose whether you want to make x or y the subject from knew of the equations
Answer:
14x-56y-42
Step-by-step explanation:
Given data
We have the expression
7(2x - 8y - 6)
Open the bracket we have
14x-56y-42
Hence the equivalent expression is
14x-56y-42
