Answer:
The solution is -10
Step-by-step explanation:
We first solve for v in the equation;
5v + 9 = 4
5v = 4 - 9
5v = -5
v = -1
Finally, we substitute v = -1 in the given expression;
3v - 7
3(-1) - 7 = -10
Answer:
-10 is the answer.
Step-by-step explanation:
We have given equation:
5v +9=4
We have to find the value of 3v-7.
To find the value of v we use the given equation.
5v +9=4
5v = 4-9
5v = -5
v = -1
Putting v = -1 in the equation 3v-7 to get the required answer.
3v-7 = 3(-1)-7
3v-7 = -3-7
3v-7 = -10 is the solution.
