Express x in terms of y where 4*x+6*y=-7
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
4*x+6*y = -7
Looking for similar summands in the left part:
4*x + 6*y = -7
Move the summands with the other variables
from left part to right part, we given:
$$4 x = - 6 y - 7$$
Divide both parts of the equation by 4
x = -7 - 6*y / (4)
We get the answer: x = -7/4 - 3*y/2
7 3*re(y) 3*I*im(y)
x1 = - - - ------- - ---------
4 2 2
$$x_{1} = - \frac{3 \operatorname{re}{\left(y\right)}}{2} - \frac{3 i \operatorname{im}{\left(y\right)}}{2} - \frac{7}{4}$$
x1 = -3*re(y)/2 - 3*i*im(y)/2 - 7/4
