Value of x
For an isosceles triangle two sides are equal
AB=BC
7x-3=9x-11.
11-3=9x-7x
8=2x
2x=8
x=8/2
x=4
AB =7x-3=7(4)-3=25 units
BC=9x-11=9(4)-11=25 units
AC=4x+1=4(4)+1=17 units
Hello! :)
Answer:
![\boxed{X=11}](https://tex.z-dn.net/?f=%5Cboxed%7BX%3D11%7D)
*The answer must have a POSITIVE sign!*
Step-by-step explanation:
Expand with distributive property: a(b+c)=ab+ac
4*5=20
6*4=24
20x-24
2*8=16
2*10=20
16x+20
20x-24=16x+20
First, you add by 24 both sides of an equation.
20x-24+24=16x+20+24
20x=16x+44
You subtract by 16x both sides of an equation.
20x-16x=16x+44-16x
4x=44
Then, you divide by 4 both sides of an equation.
4x/4=44/4
Divide by the numbers from left to right.
44/4=11
<u><em>X=11 is the final answer</em></u>
Hope this helps!
Have a nice day! :)
