18x-15-2\left(4x+13\right)+5=5\left(4-x\right)-26
Use the distributive property to multiply 3 by 6x-5.
18x-15-8x-26+5=5\left(4-x\right)-26
Use the distributive property to multiply -2 by 4x+13.
10x-15-26+5=5\left(4-x\right)-26
Combine 18x and -8x to get 10x.
10x-41+5=5\left(4-x\right)-26
Subtract 26 from -15 to get -41.
10x-36=5\left(4-x\right)-26
Add -41 and 5 to get -36.
10x-36=20-5x-26
Use the distributive property to multiply 5 by 4-x.
10x-36=-6-5x
Subtract 26 from 20 to get -6.
10x-36+5x=-6
Add 5x to both sides.
15x-36=-6
Combine 10x and 5x to get 15x.
15x=-6+36
Add 36 to both sides.
15x=30
Add -6 and 36 to get 30.
x=\frac{30}{15}
Divide both sides by 15.
x=2
Divide 30 by 15 to get 2.
