Multiply all terms by 2 to get rid of fractions
2x+10=28-x
Add x to both sides
3x+10=28
Subtract 10 from both sides
3x=18
Divide both sides by 3
x=6
Final answer: x=6
Answer:
multiply (x-1) to both sides and then subtract three from both sides
3 = (x-1)(x+1)
3 = (x^2 -1)
0 = x^2 - 4
(x-2)(x+2) = 0
x = 2
x = -2
Step-by-step explanation:
QR || ST & QT=RS
That could be an isosceles trapezoid. Don't check this one.
QR=ST & QR || ST
Congruent Parallel sides. CHECK ME.
QT || RS & QR=ST.
Basically the same as the first, don't check.
QR=ST & QT=RS
Quadrilateral with equal opposite sides is a parallelogram. CHECK ME
QR=ST & ST=ST
ST=ST is not news. Congruent opposite sides. Don't check me.
