Solve in Q in the equation 2+3x=7
Weegy: In answer to Your Question: Solution Set would be the values found for x%5B1%5D , [ x%5B2%5D x%5E2-3x=7 Written as an Quadratic Equation: x%5E2-3x-7=0 . Using the Quadratic Formula to Solve: x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+ . Solved by pluggable solver: SOLVE quadratic equation with variable Quadratic equation ax%5E2%2Bbx%2Bc=0 (in our case 1x%5E2%2B-3x%2B-7+=+0) has the following solutons: x%5B12%5D+=+%28b%2B-sqrt%28+b%5E2-4ac+%29%29%2F2%5Ca For these solutions to exist, the discriminant b%5E2-4ac should not be a negative number. First, we need to compute the discriminant b%5E2-4ac: b%5E2-4ac=%28-3%29%5E2-4%2A1%2A-7=37. Discriminant d=37 is greater than zero. That means that there are two solutions: +x%5B12%5D+=+%28- 3%2B-sqrt%28+37+%29%29%2F2%5Ca. x%5B1%5D+=+%28-%28-3%29%2Bsqrt%28+37+%29%29%2F2%5C1+=+4.54138126514911 x%5B2%5D+=+%28-%28-3%29-sqrt%28+37+%29%29%2F2%5C1+=+-1.54138126514911 Quadratic expression 1x%5E2%2B-3x%2B-7 can be factored: 1x%5E2%2B-3x%2B-7+=+1%28x-4.54138126514911%29%2A%28x- 1.54138126514911%29 Again, the answer is: 4.54138126514911, -1.54138126514911. Here's your graph: graph%28+500%2C+500%2C+-10%2C+10%2C+-20%2C+20%2C+1%2Ax%5E2%2B-3%2Ax%2B-7+%29 ] (More)

2 + 3x = 7;

3x = 7 - 2;

3x = 5;

x = 5/3

tektek10, please make sure to not miss a single step on solutions for equations. It's important that a solution is complete so the user would understand clearly.

Okay, I thought that dividing the variable on the right side right after subtraction would be enough as answer.
Added 5/7/2014 5:24:00 PM
Yes, but it you didn't show the answer to 7 - 2 , you skipped to division right away, but it's not a big deal.

It would just be more helpful to show complete solutions.
