4x+2y=9,8x+2y=14

Solution

4 x + 2 y = 9, 8 x + 2 y = 14

Solution

x = \frac{5}{4}, y = 2

Solution steps

[4 x + 2 y = 9 8 x + 2 y = 14]

Isolate

x

for

4 x + 2 y = 9 : x = \frac{9 - 2 y}{4}

Substitute

x = \frac{9 - 2 y}{4}

[8 \cdot \frac{9 - 2 y}{4} + 2 y = 14]

Simplify

[- 2 y + 18 = 14]

Isolate

y

for

- 2 y + 18 = 14 : y = 2

For

x = \frac{9 - 2 y}{4}

Substitute

y = 2

x = \frac{9 - 2 \cdot 2}{4}

Simplify

x = \frac{5}{4}

The solutions to the system of equations are:

x = \frac{5}{4}, y = 2

Popular Examples

x= 17/11 ,z= 4/121

x = \frac{17}{11}, z = \frac{4}{121}

2x-y-z=2,x+y=3,x-y+z=2

2 x - y - z = 2, x + y = 3, x - y + z = 2

y+1=2,(x-1)ey-1=x+1

y + 1 = 2, (x - 1) ey - 1 = x + 1

3x+y=1,(2k-1)x+(k-1)y=(2k-1)

3 x + y = 1, (2 k - 1) x + (k - 1) y = (2 k - 1)

2x-y=11,5x+4y=1

2 x - y = 11, 5 x + 4 y = 1
