Find the value of x 6x - 1 42 10x+5 78

6x-1=42=10x+5=78

We move all terms to the left:

6x-1-(42)=0

We add all the numbers together, and all the variables

6x-43=0

We move all terms containing x to the left, all other terms to the right

6x=43

x=43/6

x=7+1/6

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.

47 - 90 = 43

43 - 180 = x

x = 137
