Answer:
[tex]\frac{2}{5}[/tex] × B + A
Step-by-step explanation:
Given equations are [tex]\frac{2}{5}[/tex]x + y = 12 ---------(A)
and equation [tex]\frac{5}{2}[/tex]y - x = 6 -------------(B)
To eliminate the variable x we will multiply equation A by [tex]\frac{5}{2}[/tex]
and add it to equation B.
In other words, the expression that we will adopt to eliminate the variable x will be [tex]\frac{2}{5}[/tex] × B + A
