Question

If the perimeter of the triangle is 49, find the value of x

Answer 1

Hello!

Let's write this as the equation below.

4x-1+4x+2+3x+4=49

Let's simplify this by combining like terms.

11x-1+2+4

11x+5=49

We subtract 5 from both sides.

11x=44

We divide both sides by 11.

x=4

I hope this helps!

Answer 2

The value of x is 4. First add up all the variables 4x+4x+3x= 11x.After that add up all the other number 4+2-1=5

11x+5=49 subtract 5 from both sides
-5=-5
11x=44
divide by 11 to both sides
44/11= 4
x=4
now plug 4 to x
4(4)-1+4(4)+2+3(4)+4
15+ 18+16=49
