Solve for x
2x+9 = 5x+4

x = 5/3

Step-by-step explanation:

1. Ok, so first, write out the given equation

2x+9 = 5x+4

2. Next, combine like terms by subtracting 5x from 2x.

-3x + 9 = 4

3. Then, subtract 9 from 4, since whatever you do to one side you have to do to the other.

-3x = -5

4. Finally, divide both sides by -3.

x = 5/3 <Answer

You're done! Hope you have a great day!

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a
