Question

help

Answer 1

x+5y = 57

x = 57-5y

-3(x) + 4y = 95

so whats x and y?

Answer 2

from your second equation, we can write:
\[x=57-5y\]
now I substitute that expression for y, into your first equation, and I get:
\[-3(57-5y)+4y=95\]
which can be easily solved for y

Answer 3

If we solve that equation, we get:
\[-171+15y+4y=95\]
\[19 y=266\]
and then:
\[y=\frac{ 266 }{ 19 }=4\]

Answer 4

now I substitute y=4 in the above expression for x, namely:
x=57-5y\[x=57-5*14==57-70=-13\]
so x=-13 and y=14
please, is my reasoning clear for you?
