Mathematics
1 answer:
finlep [7]3 years ago
5 0

Answer:

One solution x=2

Step-by-step explanation:

Given the equation

0.5(x+12)=4x-1

First, multiply this equation by 10:

10\cdot 0.5(x+12)=10(4x-1)\\ \\5(x+12)=40x-10\\ \\5x+60=40x-10

Separate terms with x and without x in different parts of the equation:

5x-40x=-10-60\\ \\-35x=-70\\ \\35x=70\\ \\x=\dfrac{70}{35}\\ \\x=2
