3q+2q=21,7p+4q=47

3 q + 2 q = 21, 7 p + 4 q = 47

p = \frac{151}{35}, q = \frac{21}{5}

Solution steps

[3 q + 2 q = 21 7 p + 4 q = 47]

Isolate

q

for

3 q + 2 q = 21 : q = \frac{21}{5}

Substitute

q = \frac{21}{5}

[7 p + 4 \cdot \frac{21}{5} = 47]

Simplify

[7 p + \frac{84}{5} = 47]

Isolate

p

for

7 p + \frac{84}{5} = 47 : p = \frac{151}{35}

The solutions to the system of equations are:

p = \frac{151}{35}, q = \frac{21}{5}

4 x + y = 7, 2 x - y = 12

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

3 x - 5 y - 6 = 2, x + 3 y - 6 = 0

2 x + 3 y = 32, 11 y - 9 x = 3

x - 4 y = - 5, 3 x - 8 y = 1
