10 – 2x + 3 = 5x – 9 + 4x

please help me solve this equation

x=2

Step-by-step explanation:

Hi there!

Whenever we're solving an algebraic equation, our goal is always to isolate the variable, which in this case is x. We would do this by performing inverse operations on both sides of the equal sign to cancel values out.

Combine like terms on both sides of the equal sign

Add 2x to both sides to cancel out -2x (addition is the inverse of subtraction)

Add 9 to both sides to cancel out -9 and isolate 11x (addition is the inverse of subtraction)

Divide both sides by 11 to isolate x (division is the inverse of multiplication)

Therefore, x=2.

I hope this helps!

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
