x=1

Explanation:

1 Expand:
6-10x+15=4x+7

2 Simplify 6-10x+15 to -10x+21:
-10x+21=4x+7

3 Add 10x to both sides:
21=4x+7+10x

4 Simplify 4x+7+10x to 14x+7:
21=14x+7

5 Subtract 7 from both sides:
21-7=14x

6 Simplify 21-7 to 14
14=14x

7 Divide both sides by 14:
1=x

8 Switch sides:
x=1

x = 1

Explanation:

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

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

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

Subtract color(blue)7 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!
