4x+10-\left(3x-4\right)=29
Use the distributive property to multiply 2 by 2x+5.
4x+10-3x-\left(-4\right)=29
To find the opposite of 3x-4, find the opposite of each term.
4x+10-3x+4=29
The opposite of -4 is 4.
x+10+4=29
Combine 4x and -3x to get x.
x+14=29
Add 10 and 4 to get 14.
x=29-14
Subtract 14 from both sides.
x=15
Subtract 14 from 29 to get 15.
