Express x in terms of y where 20*x+14*y=16
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
20*x+14*y = 16
Looking for similar summands in the left part:
14*y + 20*x = 16
Move the summands with the other variables
from left part to right part, we given:
$$20 x = 16 - 14 y$$
Divide both parts of the equation by 20
x = 16 - 14*y / (20)
We get the answer: x = 4/5 - 7*y/10
4 7*re(y) 7*I*im(y)
x1 = - - ------- - ---------
5 10 10
$$x_{1} = - \frac{7 \operatorname{re}{\left(y\right)}}{10} - \frac{7 i \operatorname{im}{\left(y\right)}}{10} + \frac{4}{5}$$
x1 = -7*re(y)/10 - 7*i*im(y)/10 + 4/5
