2x=18-4y,3x=7y-12

Solution

2 x = 18 - 4 y, 3 x = 7 y - 12

Solution

x = 3, y = 3

Solution steps

[2 x = 18 - 4 y 3 x = 7 y - 12]

Isolate

x

for

2 x = 18 - 4 y : x = 9 - 2 y

Substitute

x = 9 - 2 y

[3 (9 - 2 y) = 7 y - 12]

Isolate

y

for

3 (9 - 2 y) = 7 y - 12 : y = 3

For

x = 9 - 2 y

Substitute

y = 3

x = 9 - 2 \cdot 3

Simplify

x = 3

The solutions to the system of equations are:

x = 3, y = 3

3x+4y=13,4x+3x=15

3 x + 4 y = 13, 4 x + 3 x = 15

-4x+3y=-4,-8x+5y=0

- 4 x + 3 y = - 4, - 8 x + 5 y = 0

x+y=60,16x+20y=1100

x + y = 60, 16 x + 20 y = 1100

-2x+y=-4,2x-3y=8

- 2 x + y = - 4, 2 x - 3 y = 8

x+16-3x+8y=23,y=4

x + 16 - 3 x + 8 y = 23, y = 4
