Question

WORKOT 7.6
1. Solve: 7 = 4x - 9
3. Solve: 3x + 5 = 13-X
5. Is p= 2 a solution for 2p - 1 = 3?
2. Solve: 12 = 22 - 5y
4. Solve: 36x + 2) - 20x-1)=7​

Answer 1

Answer:

1. 7= 4x-9

7+9= 4x

16= 4x

16/4= x

4=x

2. 3x+5=13-x

3x+x= 13-5

4x=8

x= 8/4

x= 2

Answer 2

$\huge \tt \: 1. \: \: 4x = 16$

$\huge \tt \: x = 4$

$\huge \tt \:3. \: \: \: \: \: 4x = 8$

$\huge \tt \: x = 2$

$\huge \tt5. \: \: 2(2) - 1 = 3$

$\huge \tt \: 3 = 3$

$\huge \tt2. \: \: \: 5y = 10$

$\huge \tt \: y = 2$
