Question

solve it 7x+3=3x-7
solve it p/10 = 2p -19​

Answer 1

Step-by-step explanation:

7x+3=3x-7

7x-3x=-7-3

4x=-10

x=-5/2

p/10=2p-19

p=20p-190

20p-p=190

19p=190

p=190/19

p=10

Answer 2

1.

$7x + 3 = 3x - 7 \\ 7x - 3x = - 7 - 3 \\ 4x = - 10 \\ \\ x = - \frac{ 10}{4} \\ \\ x = - \frac{ 5}{2}$

2.

$\frac{p}{10} = 2p - 19 \\ \\ p = 10(2p - 19) \\ p = 20p - 190 \\ 20p - p = 190 \\ 19p = 190 \\ p = \frac{190}{19} \\ \\ p = 10$
