x+y=17,4x-y=43

Solution

x + y = 17, 4 x - y = 43

Solution

x = 12, y = 5

Solution steps

[x + y = 17 4 x - y = 43]

Isolate

x

for

x + y = 17 : x = 17 - y

Substitute

x = 17 - y

[4 (17 - y) - y = 43]

Simplify

[68 - 5 y = 43]

Isolate

y

for

68 - 5 y = 43 : y = 5

For

x = 17 - y

Substitute

y = 5

x = 17 - 5

Simplify

x = 12

The solutions to the system of equations are:

x = 12, y = 5

Popular Examples

x + y = 20, x - y = - 6

x + 2 y = 2, x - 2 y = 6

5 x - y = 4, 2 x - y = - 5

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

((x+3))/y =2,((y+6))/x =-1

\frac{( x + 3 )}{y} = 2, \frac{( y + 6 )}{x} = - 1
