Answer:

x=3

Step-by-step explanation:

distribute the 4 to get 8x-28 and then bring down the -2x

8x-28-2x= -10 combine like terms to get 6x-28= -10

add 28 to both sides to get 6x=18

divide both sides by 6 to get x=3

What is the length of ac help pls

Lelu [443]

Answer:

x=2

Step-by-step explanation:

This is an isosceles triangle you can tell by the two congruent/equal angles

angle A is congruent/equal to angle C by definition the two sides will be equal.

x-4=3x-8

1. get all you x's on one side. by subtracting x from both sides you don't have to deal with dividing by negatives later on.

x-x-4=3x-x-8

-4=2x-8

now you want to get x by itself so add 8 to both sides

4= 2x

x is still not by itself so divide both sides by 2

x=2

4x + 3 = 4x + 15 solve for x Plese help

ira [324]

4x - 15 = 3 
4x = 3 + 15 
4x = 18 (divide both sides by 4 to get x) 
4x/4 = 18/4 
x = 4.5
