Answer: x=7

Step-by-step explanation:

3x − 2 + 7x − 45= 23

10x-47=23

Add 47 on both sides

10x-47+47=23+47

10x=70

Divide 10 on both sides

10x/10=70/10

x=7

Answer:

x = 7

Step-by-step explanation:

3x - 2 + 7x - 45 = 23

Combine like terms

10x - 47 = 23

Isolate 10x.

10x = 23 + 47

= 70

Find x.

x = 70 ÷ 10

= 7
