Answer:
x=3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4x+x+3=18
(4x+x)+(3)=18(Combine Like Terms)
5x+3=18
5x+3=18
Step 2: Subtract 3 from both sides.
5x+3−3=18−3
5x=15
Step 3: Divide both sides by 5.
5x/5 = 15/5
x=3
Subtract 4 from both sides of the equation
you will end up with 2/7x=4
next multiply 7x by both sides
you will end up with 2=28x
next divide 28 from both sides
you will end up with x=1/14 in
fraction form. Hope this helps.
Considering they are congruent
if 7x-19=2x+11
how much is 6x-8
7x-19=2x+11
7x=2x+30
7x-2x=30
5x=30
X=6
6x-8=
(6*X)-8=
(6*6)-8=
36-8=
28
therefore
BC= 28
2x+11
(2*6)+11
12+11
23
23+28+24=75
therefore the perimeter is 75
