Question

i need help i don't know how to do this

Answer 1

Answer:

1.

58 + (6x + 2) = 180

6x + 2 = 180 - 58

6x + 2 = 122

6x = 120

x = 120 ÷ 6

x = 20

( 3x + 6 ) + 48 = 90

3x + 6 = 90 - 48

3x + 6 = 42

3x = 36

x = 6

(2x + 9 ) + (3x + 1)= 90

2x( 3x + 1) + 9 ( 3x + 1) = 90

6x² + 2x + 27x + 9 = 90

6x² + 29x = 90 - 9

6x² + 29x = 81

solve it by formula method of Factorisation

Answer 2

20

Step-by-step explanation:

6x+60=180

6x=180-60

6x=120

x=120/6

x=20

3x+6+48=90

3x+54=90

3x=90-54

=36

3x=36/3=12

2x+9+3x+1=90

5x+10=90

5x=90-10

5x=80

x=80/5

x=16
