2x+y=3,x-5y=40

Solution

2 x + y = 3, x - 5 y = 40

Solution

x = 5, y = - 7

Solution steps

[2 x + y = 3 x - 5 y = 40]

Isolate

x

for

2 x + y = 3 : x = \frac{3 - y}{2}

Substitute

x = \frac{3 - y}{2}

[\frac{3 - y}{2} - 5 y = 40]

Simplify

[\frac{3 - 11 y}{2} = 40]

Isolate

y

for

\frac{3 - 11 y}{2} = 40 : y = - 7

For

x = \frac{3 - y}{2}

Substitute

y = - 7

x = \frac{3 - ( - 7 )}{2}

\frac{3 - ( - 7 )}{2} = 5

x = 5

The solutions to the system of equations are:

x = 5, y = - 7

2 x + y = 35, 3 x + 4 y = 65

y = 0, x = 1, x = 2

a + b = 20, a - b = 4

b*a_{1}=20,iq=-2

b \cdot a_{1} = 20, i q = - 2

2 x + y = 8, y = - x + 5
