3x+5y=38,3x-y=-4

Solution

3 x + 5 y = 38, 3 x - y = - 4

Solution

x = 1, y = 7

Solution steps

[3 x + 5 y = 38 3 x - y = - 4]

Isolate

x

for

3 x + 5 y = 38 : x = \frac{38 - 5 y}{3}

Substitute

x = \frac{38 - 5 y}{3}

[3 \cdot \frac{38 - 5 y}{3} - y = - 4]

Simplify

[38 - 6 y = - 4]

Isolate

y

for

38 - 6 y = - 4 : y = 7

For

x = \frac{38 - 5 y}{3}

Substitute

y = 7

x = \frac{38 - 5 \cdot 7}{3}

Simplify

x = 1

The solutions to the system of equations are:

x = 1, y = 7

11 x + 5 y = 7, 6 x - 3 y = 21

6x+5y=4,0.2x+0.3y=2

6 x + 5 y = 4, 0.2 x + 0.3 y = 2

3 x - y = 5, y = 7 - x

x+3y=12,3x+2y=123

x + 3 y = 12, 3 x + 2 y = 123

7x-3y=31,9x-5y=41

7 x - 3 y = 31, 9 x - 5 y = 41
