x+y=10,x=y+4

Solution

x + y = 10, x = y + 4

Solution

x = 7, y = 3

Solution steps

[x + y = 10 x = y + 4]

Substitute

x = y + 4

[y + 4 + y = 10]

Simplify

[2 y + 4 = 10]

Isolate

y

for

2 y + 4 = 10 : y = 3

For

x = y + 4

Substitute

y = 3

x = 3 + 4

Simplify

x = 7

The solutions to the system of equations are:

x = 7, y = 3

Popular Examples

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

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

x+3y+3z=2,3x+9y+3z=3,3x+6y+6z=4

x + 3 y + 3 z = 2, 3 x + 9 y + 3 z = 3, 3 x + 6 y + 6 z = 4

((2x))/9+y/6 =2, x/a-y/b =4

\frac{( 2 x )}{9} + \frac{y}{6} = 2, \frac{x}{a} - \frac{y}{b} = 4

(2x-3)/(4y)=3,x-4y+7=0

\frac{2 x - 3}{4 y} = 3, x - 4 y + 7 = 0
