x+y=13,70x+80y=980

Solution

x + y = 13, 70 x + 80 y = 980

Solution

x = 6, y = 7

Solution steps

[x + y = 13 70 x + 80 y = 980]

Isolate

x

for

x + y = 13 : x = 13 - y

Substitute

x = 13 - y

[70 (13 - y) + 80 y = 980]

Simplify

[910 + 10 y = 980]

Isolate

y

for

910 + 10 y = 980 : y = 7

For

x = 13 - y

Substitute

y = 7

x = 13 - 7

Simplify

x = 6

The solutions to the system of equations are:

x = 6, y = 7

Popular Examples

y - x = 4, y - 2 x = 3

x+3y=15,3x+6y=18

x + 3 y = 15, 3 x + 6 y = 18

a = 3, c = 3

a = 3, c = 4

-3x+2y=2,2x-2y=-4

- 3 x + 2 y = 2, 2 x - 2 y = - 4
