### Subject: Algebra

Solve this quadratic equation for the value of x: x+(3x-2)=18

Solve: x+(3x-2)=18 x+3x-2=18 4x-2=18 4x-2+2=18+2 4x=20 4x/4=20/4 x=5 1. Use PEMDAS Rule: parenthesis, exponents, multiplication, division, addition, subtraction. PEMDAS tells you what operations in the expression to complete first. Since there are no like terms in the parenthesis we cannot operate on that and move on to the next operations in PEMDAS. 2.Since there are no more we can use, we shall use commutative property to change the order of the operations to make it easier to solve. 3. Now combine like terms. 4. Solve for x by adding 2 to each side. 5. Now we must solve for x, we do this by dividing by 4, which is the coefficient for x. 6. After dividing we get x=5 Check Answer: x+(3x-2)=18; when x=5 5+[3(5)-2]=18 1. Substitute x for 5 to check if the answer is correct. 5+(15-2)=18 2. Use PEMDAS, solve the operation in the parenthesis by multiplying 3(5)=15 5+13=18 3. Use PEMDAS again to solve the operation in the parenthesis 18=18 4. Addiction The solution is correct as 18=18 :)
