if i am 9 and you are 10, how old are we together?

Well we would be either 19 or 9 1/2.

Step-by-step explanation:

This is how I would do this.

9 1/2

Step-by-step explanation:

that's what I'll do

step-by-step explanation:

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
