15x+3y=15,12x+4y=20

Solution

15 x + 3 y = 15, 12 x + 4 y = 20

Solution

x = 0, y = 5

Solution steps

[15 x + 3 y = 15 12 x + 4 y = 20]

Isolate

x

for

15 x + 3 y = 15 : x = \frac{5 - y}{5}

Substitute

x = \frac{5 - y}{5}

[12 \cdot \frac{5 - y}{5} + 4 y = 20]

Simplify

[\frac{60 + 8 y}{5} = 20]

Isolate

y

for

\frac{60 + 8 y}{5} = 20 : y = 5

For

x = \frac{5 - y}{5}

Substitute

y = 5

x = \frac{5 - 5}{5}

Simplify

x = 0

The solutions to the system of equations are:

x = 0, y = 5

Popular Examples

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

3x+y=12,x+5y=32

3 x + y = 12, x + 5 y = 32

12(x-6)=(y-6),12x-y=66-12,12-y=-6+72,12x-7z=y-6

12 (x - 6) = (y - 6), 12 x - y = 66 - 12, 12 - y = - 6 + 72, 12 x - 7 z = y - 6

2x+3y=8,3x+4y=11

2 x + 3 y = 8, 3 x + 4 y = 11

4 x - 2 y = 4, x - y = 6
