x-3y=9,2y+x=4

Solution

x - 3 y = 9, 2 y + x = 4

Solution

x = 6, y = - 1

Solution steps

[x - 3 y = 9 2 y + x = 4]

Isolate

x

for

x - 3 y = 9 : x = 9 + 3 y

Substitute

x = 9 + 3 y

[2 y + 9 + 3 y = 4]

Simplify

[5 y + 9 = 4]

Isolate

y

for

5 y + 9 = 4 : y = - 1

For

x = 9 + 3 y

Substitute

y = - 1

x = 9 + 3 (- 1)

9 + 3 (- 1) = 6

x = 6

The solutions to the system of equations are:

x = 6, y = - 1

4x-3y=18,2x+5y=-4

4 x - 3 y = 18, 2 x + 5 y = - 4

y = 2 x, x + y = 12

n + 65 = 8, 7 n = 27

92x-3y+8=0,x-4y+7=0

92 x - 3 y + 8 = 0, x - 4 y + 7 = 0

x+y=7,0.5x+12y=7

x + y = 7, 0.5 x + 12 y = 7
