x+4y=3,x+2y=5

Solution

x + 4 y = 3, x + 2 y = 5

Solution

x = 7, y = - 1

Solution steps

[x + 4 y = 3 x + 2 y = 5]

Isolate

x

for

x + 4 y = 3 : x = 3 - 4 y

Substitute

x = 3 - 4 y

[3 - 4 y + 2 y = 5]

Simplify

[3 - 2 y = 5]

Isolate

y

for

3 - 2 y = 5 : y = - 1

For

x = 3 - 4 y

Substitute

y = - 1

x = 3 - 4 (- 1)

3 - 4 (- 1) = 7

x = 7

The solutions to the system of equations are:

x = 7, y = - 1

7x+4y=26,3x-4y=4

7 x + 4 y = 26, 3 x - 4 y = 4

3x+2y=1,2-2x+y=-8

3 x + 2 y = 1, 2 - 2 x + y = - 8

5x-4y=-1,0y=2x-5

5 x - 4 y = - 1, 0 y = 2 x - 5

y=3x-5,2x-y+1=0

y = 3 x - 5, 2 x - y + 1 = 0

2x-3y+2=0,6x+9y+5=0

2 x - 3 y + 2 = 0, 6 x + 9 y + 5 = 0
