Here's the kind of process you can use to find out:
Write the equation, so you can look at it:
7x + 2 = 4x - 3
Subtract 4x from each side of the equation:
3x + 2 = -3
Subtract 2 from each side:
3x = -5
Divide each side by 3:
x = - 5/3

x2+11x+11 = 7x+9 x2+11x-7x+11-9 = 0 x2+4x+2 = 0 The above quadratic equation can be solved by using the quadratic equation formula and it will have two solutions.
7x + 8 = 10x - 2 ∴ 3x = 10 ∴ x = 10/3
Add 4x - 2 to each side: 5x = 5 x = 1
The equation 4x + 5 = 2 has the solution 4x = -3 and x = - 3/4 (minus 3/4).
4x+3y = 6 3y = -4x+6 y = -4/3x+2 in slope intercept form
