I am thinking of a number. I multiply it by 11 and subtract 78.
I get the same answer if I multiply
by 6 and subtract 8.
What is my number?

The number is 14

Step-by-step explanation:

11x - 78 = 6x - 8

11x -6x = -8 + 78

5x = 70

x = 14

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

answer: the first graph
