Express x in terms of y where 19*x+20*y=-7
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
19*x+20*y = -7
Looking for similar summands in the left part:
19*x + 20*y = -7
Move the summands with the other variables
from left part to right part, we given:
$$19 x = - 20 y - 7$$
Divide both parts of the equation by 19
x = -7 - 20*y / (19)
We get the answer: x = -7/19 - 20*y/19
7 20*re(y) 20*I*im(y)
x1 = - -- - -------- - ----------
19 19 19
$$x_{1} = - \frac{20 \operatorname{re}{\left(y\right)}}{19} - \frac{20 i \operatorname{im}{\left(y\right)}}{19} - \frac{7}{19}$$
x1 = -20*re(y)/19 - 20*i*im(y)/19 - 7/19
