  x = 12

Step-by-step explanation:

The similarity statement tells you corresponding sides have the same ratio.

  AB/BC = FE/EC

  x/10 = 6/5

  x = 10(6/5)

  x = 12

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3
