Answer:

The value of x would be 20

Step-by-step explanation:

To solve this triangle, we need to first note that all triangles have 180 degrees. So we can add these all together and set equal to 180.

40 + 3x + 4x = 180

40 + 7x = 180

7x = 140

x = 20

Answer:

x=4.375

Step-by-step explanation:

-3(2x-7)+5=2x-9

-6x+21+5=2x-9

-6x+26=2x-9

-6x-2x+26=2x-2x-9

-8x+26=-9

-8x+26-26=-9-26

-8x=-35

-8x/-8=-35/-8

x=4.375
