x+y=7,6x+5y=9

Solution

x + y = 7, 6 x + 5 y = 9

Solution

x = - 26, y = 33

Solution steps

[x + y = 7 6 x + 5 y = 9]

Isolate

x

for

x + y = 7 : x = 7 - y

Substitute

x = 7 - y

[6 (7 - y) + 5 y = 9]

Simplify

[42 - y = 9]

Isolate

y

for

42 - y = 9 : y = 33

For

x = 7 - y

Substitute

y = 33

x = 7 - 33

Simplify

x = - 26

The solutions to the system of equations are:

x = - 26, y = 33
