If you can help pleasee

v=10

Step-by-step explanation:

these 2 angles add up to 90 degrees bc of the right angle marker

6v-3 + 4v-7 = 90

combine like terms:  6v+4v  and  -3+-7

10v -10 = 90

isolate the variable by first adding 10 on both sides to get:

10v = 100

then divide 10 on both sides to get v

v=10

u can plug in the values to make sure it's right:

4(10)-7=33

6(10)-3=57

33+57=90
