Answer:
The solution is (6.2,6.2)
Step-by-step explanation:
we have
[tex]0.4x+0.6y=6.2[/tex] ----> equation A
For variable x and y equal
[tex]x=y[/tex] ----> equation B
Solve the system by substitution
substitute equation B in equation A
[tex]0.4y+0.6y=6.2[/tex]
solve for y
combine like terms
[tex]y=6.2[/tex]
so
[tex]x=6.2[/tex]
therefore
The solution is (6.2,6.2)
