x=23/2, bc first u do the parenthesis so 4 times x is 4x, and 4 times 5 os 20, so rhen u have


4x plus -20 plus -8=18

u combine like terms, so then 4x-28=18


then u add 28 to 18, bc in algebra, u change subtraction to addition in these types of problems, so if u have sutraction, u change it to addition, and if u have addition, u change it to sutraction)

so then u have 4x=46, and then it's x=23/2

Your first step is to use the distributive property. Then just solve for x.

4(x - 5) - 8 = 18 → Given equation
4x - 20 - 8 = 18 → Distributive Property (4 × x and 4 × 5)
4x - 28 = 18 → Combine Like Terms (-20 - 8 = -28; always keep the sign if it's subtraction)
4x = 46 → Addition Property of Equality (Add 28 to both sides)
x = 11.5 or 11 ¹/₂
