2x-4y=36,4x+2y=82

Solution

2 x - 4 y = 36, 4 x + 2 y = 82

Solution

x = 20, y = 1

Solution steps

[2 x - 4 y = 36 4 x + 2 y = 82]

Isolate

x

for

2 x - 4 y = 36 : x = 2 (y + 9)

Substitute

x = 2 (y + 9)

[4 \cdot 2 (y + 9) + 2 y = 82]

Simplify

[10 y + 72 = 82]

Isolate

y

for

10 y + 72 = 82 : y = 1

For

x = 2 (y + 9)

Substitute

y = 1

x = 2 (1 + 9)

Simplify

x = 20

The solutions to the system of equations are:

x = 20, y = 1

Popular Examples

5a+b=21,2a+3b=24s

5 a + b = 21, 2 a + 3 b = 24 s

(x/5)+y+2=0,(x/3)-y-10=0

(\frac{x}{5}) + y + 2 = 0, (\frac{x}{3}) - y - 10 = 0

a = - 3, b = - 6, c = - 2

x-y=z,y=4z,x+y=81

x - y = z, y = 4 z, x + y = 81

a+b=3,b+c=4,c+a=5

a + b = 3, b + c = 4, c + a = 5
