-x+2y=1,2x+5y=25

Solution

- x + 2 y = 1, 2 x + 5 y = 25

Solution

x = 5, y = 3

Solution steps

[- x + 2 y = 1 2 x + 5 y = 25]

Isolate

x

for

- x + 2 y = 1 : x = - 1 + 2 y

Substitute

x = - 1 + 2 y

[2 (- 1 + 2 y) + 5 y = 25]

Simplify

[- 2 + 9 y = 25]

Isolate

y

for

- 2 + 9 y = 25 : y = 3

For

x = - 1 + 2 y

Substitute

y = 3

x = - 1 + 2 \cdot 3

Simplify

x = 5

The solutions to the system of equations are:

x = 5, y = 3

(3/x)/(5/2)=2,x=(3/x)/(5/2)

\frac{\frac{3}{x}}{\frac{5}{2}} = 2, x = \frac{\frac{3}{x}}{\frac{5}{2}}

b^{0.2}x+3y=7,x-y=1

b^{0.2} x + 3 y = 7, x - y = 1

x-4y=10,-2x+y=1

x - 4 y = 10, - 2 x + y = 1

-2x-7y=25,-2x-5y=19

- 2 x - 7 y = 25, - 2 x - 5 y = 19

2x+y=5,0.3x+2y=7

2 x + y = 5, 0.3 x + 2 y = 7
