x-y=3,2x+4y=12

Solution

x - y = 3, 2 x + 4 y = 12

Solution

x = 4, y = 1

Solution steps

[x - y = 3 2 x + 4 y = 12]

Isolate

x

for

x - y = 3 : x = 3 + y

Substitute

x = 3 + y

[2 (3 + y) + 4 y = 12]

Simplify

[6 + 6 y = 12]

Isolate

y

for

6 + 6 y = 12 : y = 1

For

x = 3 + y

Substitute

y = 1

x = 3 + 1

Simplify

x = 4

The solutions to the system of equations are:

x = 4, y = 1

Popular Examples

x + y = 2, 4 - 3 x + y = 0

2x-3y=8,4x-6y=9

2 x - 3 y = 8, 4 x - 6 y = 9

m = 2, b = 1

x/3 = y/2 ,2 x/(15)=20 y/5

\frac{x}{3} = \frac{y}{2}, 2 \frac{x}{15} = 20 \frac{y}{5}

2x-9y=1,4x=-6y+7

2 x - 9 y = 1, 4 x = - 6 y + 7
