2x+3y=9,4x+6y=18

Solution

2 x + 3 y = 9, 4 x + 6 y = 18

Solution

x = \frac{9 - 3 y}{2}

Solution steps

[2 x + 3 y = 9 4 x + 6 y = 18]

Isolate

x

for

2 x + 3 y = 9 : x = \frac{9 - 3 y}{2}

Substitute

x = \frac{9 - 3 y}{2}

[4 \cdot \frac{9 - 3 y}{2} + 6 y = 18]

Simplify

[18 = 18]

The solutions to the system of equations are:

x = \frac{9 - 3 y}{2}

x_{1}=-1,0yx_{2}=-2

x_{1} = - 1, 0 y x_{2} = - 2

4x+5y=21,4x+8y=-8

4 x + 5 y = 21, 4 x + 8 y = - 8

3x+2y=16,4x-5y=6

3 x + 2 y = 16, 4 x - 5 y = 6

16(3x-5)=10,(4x-8)=40

16 (3 x - 5) = 10, (4 x - 8) = 40

10x+y+z=1,2x+10y+z=1,2x+y+10z=12

10 x + y + z = 1, 2 x + 10 y + z = 1, 2 x + y + 10 z = 12
