Question

If a ll b, find the value of x. ​

Answer 1

7x+11=10x-43
-3x=-32
X=32/3

Answer 2

x = 18

Explanation:

Alternate exterior angles are congruent. Set the equations equal to each other and solve for x.

7x + 11 = 10x - 43 Subtract 7 x from both sides

7x - 7x + 11 = 10x - 7x - 43

11 = 3x - 43 Add 3 to both sides

11 + 43 = 3x -43 + 43

54 = 3x Divide both sides by 3

`(54)/(3)` =
`(3x)/(3)`

18 = x
