So 4x + 2 = 8 so 4x = 8-2 = 6 x = 6/4 = 1.5

justme
  • justme
theres no graphing in this section of our book
anonymous

Justme, the equation you submitted was not a quadratic, as it did not have a variable to a power such as:\[x ^{2}\] this is a linear equation.2(2x+1)=8 Remove the parenthesis by distributing the 2 getting 4x+2=8 then subtract 2 from both sides getting: 4x=8-2=6 We now have the value for 4x as 4x=6. However, you want the value of x. Divide both sides by 4 getting: (4/4)x=6/4 1x=3/2 or x=3/2=1 1/2
