7x+4y=30,3y+2y=14

7 x + 4 y = 30, 3 y + 2 y = 14

x = \frac{94}{35}, y = \frac{14}{5}

Solution steps

[7 x + 4 y = 30 3 y + 2 y = 14]

Isolate

y

for

3 y + 2 y = 14 : y = \frac{14}{5}

Substitute

y = \frac{14}{5}

[7 x + 4 \cdot \frac{14}{5} = 30]

Simplify

[7 x + \frac{56}{5} = 30]

Isolate

x

for

7 x + \frac{56}{5} = 30 : x = \frac{94}{35}

The solutions to the system of equations are:

x = \frac{94}{35}, y = \frac{14}{5}

7 x + 9 y = 42, 12 x + 10 y = - 4

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

x - 201 = 0, y - 202 = 0

2 x + 3 y = 19, 3 x + 2 y = 16

4 x - 3 y = 7, 5 x - 2 y = 14
