x =

Answer 1

`x=(-4y+55)/(3)`

Explanation:

`(6x+4)+(8y-7)+73=180`

Remove parentheses.

`6x+4+8y-7+73=180`

Group like terms.

`6x+8y+4-7+73=180`

Add/Subtract the numbers: 4 - 7 + 73 = 70

`6x+8y+70=180`

Subtract 8y from both sides.

`6x+8y-8y+70=180-8y`

Simplify.

`6x+70=180-8y`

Subtract 70 from both sides.

`6x+70-70=180-8y-70`

Simplify.

`6x=-8y+110`

Divide both sides by 6.

`(6x)/(6) =-(8)/(6) +(110)/(6)`

Simplify.

`x=(-4y+55)/(3)`

Answer 2

x = 5

Explanation:

Since you hace an isoceles triangle angle A is equal to angle C. So angle C is also 73°. All triangles have an internal sum of 180. So you can solve the following equation

180 - 73 - 73 = 6x + 4

34 = 6x + 4

34 - 4 = 6x

30 = 6x

x = 30 / 6

x = 5
