x = -7/46

Explanation:

First, use the distributive property to simplify color(blue)(4(4x+3)) and color(blue)(-6(5x+2)):

Following this image, we know that:
color(blue)(4(4x+3) = (4 * 4x) + (4 * 3) = 16x + 12)

and

color(blue)(-6(5x+2) = (-6*5x) - (6 * 2) = -30x - 12)

Now let's put them back into the equation:
16x + 12 - 12 = 5 - 30x - 12

Simplify:
16x = -7 - 30x

Add color(blue)(30x) to both sides of the equation:
16x quadcolor(blue)(+quad30x) = -7 - 30x quadcolor(blue)(+quad30x)

46x = -7

Divide both sides by color(blue)46:
(46x)/color(blue)46 = -7/color(blue)46

Therefore,
x = -7/46

Hope this helps!
