7x+3y=37,7x+y=31

Solution

7 x + 3 y = 37, 7 x + y = 31

Solution

x = 4, y = 3

Solution steps

[7 x + 3 y = 37 7 x + y = 31]

Isolate

x

for

7 x + 3 y = 37 : x = \frac{37 - 3 y}{7}

Substitute

x = \frac{37 - 3 y}{7}

[7 \cdot \frac{37 - 3 y}{7} + y = 31]

Simplify

[37 - 2 y = 31]

Isolate

y

for

37 - 2 y = 31 : y = 3

For

x = \frac{37 - 3 y}{7}

Substitute

y = 3

x = \frac{37 - 3 \cdot 3}{7}

\frac{37 - 3 \cdot 3}{7} = 4

x = 4

The solutions to the system of equations are:

x = 4, y = 3

4x-x=2,x-54x-x=2x-5

4 x - x = 2, x - 54 x - x = 2 x - 5

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

5a-2b=11,3a+b=11

5 a - 2 b = 11, 3 a + b = 11

3x-2y=9, x/3-y/6 = 5/6

3 x - 2 y = 9, \frac{x}{3} - \frac{y}{6} = \frac{5}{6}

2 x - y = 12, 3 x + y = 3
