Answer:(question8 x=28),(question9 x=18),(question10 x=22),(question11 x=45)

Step-by-step explanation:

Question 8

2x+1+33=90

2x+34=90

2x=90-34

2x=56

Divide both sides by 2

x=56/2

x=28

Question 9

3x+11+25+90=180

3x+126=180

3x=180-126

3x=54

Divide both sides by 3

x=54 ➗ 3

x=18

Question 10

5x+12=6x-10

Collect like terms

6x-5x=12+10

x=22

Question 11

45+3x=180

3x=180-45

3x=135

Divide both sides by 3

x=135 ➗ 3

x=45
