Express x in terms of y where 14*x+10*y=-4
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
14*x+10*y = -4
Looking for similar summands in the left part:
10*y + 14*x = -4
Move the summands with the other variables
from left part to right part, we given:
$$14 x = - 10 y - 4$$
Divide both parts of the equation by 14
x = -4 - 10*y / (14)
We get the answer: x = -2/7 - 5*y/7
2 5*re(y) 5*I*im(y)
x1 = - - - ------- - ---------
7 7 7
$$x_{1} = - \frac{5 \operatorname{re}{\left(y\right)}}{7} - \frac{5 i \operatorname{im}{\left(y\right)}}{7} - \frac{2}{7}$$
x1 = -5*re(y)/7 - 5*i*im(y)/7 - 2/7
