How to use it?
- Express {x} in terms of y where:
- 16*x+7*y=8
- -11*x+4*y=-8
- 17*x-11*y=2
- -14*x+1*y=3
- Equation:
-
Equation cos(x)-sin(x)=0
-
Equation (7-x)^2=(x+16)^2
-
Equation -9(8-9x)=4x+5
-
Equation sin(pi*x)=1
-
Identical expressions
- sixteen *x+ seven *y= eight
- 16 multiply by x plus 7 multiply by y equally 8
- sixteen multiply by x plus seven multiply by y equally eight
- 16x+7y=8
-
Similar expressions

The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move the summands with the other variables
from left part to right part, we given:
$$16 x = 8 - 7 y$$
Divide both parts of the equation by 16
We get the answer: x = 1/2 - 7*y/16
16*x+7*y = 8
Looking for similar summands in the left part:
7*y + 16*x = 8
Move the summands with the other variables
from left part to right part, we given:
$$16 x = 8 - 7 y$$
Divide both parts of the equation by 16
x = 8 - 7*y / (16)
We get the answer: x = 1/2 - 7*y/16

$$x_{1} = - \frac{7 \operatorname{re}{\left(y\right)}}{16} - \frac{7 i \operatorname{im}{\left(y\right)}}{16} + \frac{1}{2}$$
x1 = -7*re(y)/16 - 7*i*im(y)/16 + 1/2
