Question

Variable on one side:

1) Solve 2x + 4 = 17.

2) Solve 3x-9-20.

3) Solve 4x-5=15.

4) Solve 6x + 12 = 54.​

Answer 1

Answer:

1) 2x = 17-4

2x = 13

x = 13/2

x = 6.5

2) 3x = 20+9

3x = 29

x = 29/3

x = 9.76

3) 4x = 15+5

4x = 20

x = 20/4

x = 5

4) 6x = 54-12

6x = 42

x = 42/6

x = 7

Answer 2

Answer:

6.5,9.67,5,7

Step-by-step explanation:

1)2x+4=17

or,2x=13

or,x=13/2

=6.5

2)3x-9=20

or,3x=29

or,x=29/3

=9.67

3)4x-5=15

or,4x=20

or,x=20/4

=5

4)6x+12=54

or,6x=42

or,x=42/6

=7
