A x=3.1
Step-by-step explanation:
1/2 (4x+6) = -5x+24.7
Multiply each side by 2 to get rid of the fraction
2*1/2 (4x+6) = 2 (-5x+24.7)
4x+6 = - 10x + 49.4
Add 10x to each side
4x+6+10x=-10x+10x+49.4
14x + 6 = 49.4
Subtract 6 from each side
14x+6-6 = 49.4-6
14x = 43.4
Divide each side by 14
14x/14 = 43.4/14
x = 3.1
