x=1x=1

Explanation:

11 Expand:
6-10x+15=4x+7610x+15=4x+7

22 Simplify 6-10x+15610x+15 to -10x+2110x+21:
-10x+21=4x+710x+21=4x+7

33 Add 10x10x to both sides:
21=4x+7+10x21=4x+7+10x

44 Simplify 4x+7+10x4x+7+10x to 14x+714x+7:
21=14x+721=14x+7

55 Subtract 77 from both sides:
21-7=14x217=14x

66 Simplify 21-7217 to 1414
14=14x14=14x

77 Divide both sides by 1414:
1=x1=x

88 Switch sides:
x=1x=1

x = 1x=1

Explanation:

6-5(2x-3) = 4x + 765(2x3)=4x+7

Distribute:
6-10x + 15 = 4x + 7610x+15=4x+7

Simplify the left side:
21 - 10x = 4x + 72110x=4x+7

Subtract color(blue)77 from both sides of the equation:
21 - 10x quadcolor(blue)(-quad7) = 4x + 7 quadcolor(blue)(-quad7)

14 - 10x = 4x

Add color(blue)(10x) to both sides of the equation:
14 - 10x quadcolor(blue)(+quad10x) = 4x quadcolor(blue)(+quad10x)

14 = 14x

Divide both sides by color(blue)14:
14/color(blue)14 = (14x)/color(blue)14

1 = x

So
x = 1

Hope this helps!
