x+y=60,16x+20y=1100

x + y = 60, 16 x + 20 y = 1100

x = 25, y = 35

Solution steps

[x + y = 60 16 x + 20 y = 1100]

Isolate

x

for

x + y = 60 : x = 60 - y

Substitute

x = 60 - y

[16 (60 - y) + 20 y = 1100]

Simplify

[960 + 4 y = 1100]

Isolate

y

for

960 + 4 y = 1100 : y = 35

For

x = 60 - y

Substitute

y = 35

x = 60 - 35

Simplify

x = 25

The solutions to the system of equations are:

x = 25, y = 35

- 2 x + y = - 4, 2 x - 3 y = 8

x + 16 - 3 x + 8 y = 23, y = 4

5 x - 21 = 8 y, - 5 y + 10 x = 15

x - 5 y = 11, 2 x + 34 = 0

16 x - 49 y = 25, 2 x - 33 y = 12
