Use the elimination method to solve the system of equations.choose the correct ordered pair.
fgiga [73]
If we subtract the equations we can eliminate the 2 6y's
subtractiong the second from the first:-

10x = 44
x = 4.4
now plug x = 44 into the first equation:-
4*4.4 + 6y = 62
6y = 62 - 4*4.4 =  44.4
y = 44.4/6 = 7.4

the answer is the order pair (4.4,7.4)

Can i please get help with this question?
poizon [28]

x . 6 = \frac{3}{8}


Pass 6 as division


x = \frac{\frac{3}{8}}{6}


As we know:


\frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a.d}{b.c}


So,


x = \frac{3}{8.6}

x = \frac{3}{48}

Simplify by 3

x = \frac{1}{16}
