x+y=7,25x+18y=147

Solution

x + y = 7, 25 x + 18 y = 147

Solution

x = 3, y = 4

Solution steps

[x + y = 7 25 x + 18 y = 147]

Isolate

x

for

x + y = 7 : x = 7 - y

Substitute

x = 7 - y

[25 (7 - y) + 18 y = 147]

Simplify

[175 - 7 y = 147]

Isolate

y

for

175 - 7 y = 147 : y = 4

For

x = 7 - y

Substitute

y = 4

x = 7 - 4

Simplify

x = 3

The solutions to the system of equations are:

x = 3, y = 4

Popular Examples

5/y-2/x =1,(3/836)/x-(24)/y =1

\frac{5}{y} - \frac{2}{x} = 1, \frac{\frac{3}{836}}{x} - \frac{24}{y} = 1

7(y+3)-2(x+3)=14,4(y-2)+3(x-3)=2

7 (y + 3) - 2 (x + 3) = 14, 4 (y - 2) + 3 (x - 3) = 2

x + y = 10, 2 x - y = 5

x + y = 10, 2 x - y = 8

x - 4 = 5 x + 16, y = 10
