Answer:
The value is -55
In the equation x-10=-15, x is equal to -5.
Therefore, the value of x is plugged into the second equation and the value found is -55.
Answer:
x = -55
Step-by-step explanation:
We know that x - 10 = -15 and we want to find the value of 5x - 30 but our first step would be to find the value x so then we can can substitute that back into the expression so
x - 10 = -15
⇔ Add -10 to both sides to isolate x
x = -5
So now we know that value of 'x' is -5 we can substitute it back into the expression 5x - 30 so
5x - 30
→ Substitute x = -5 back into it
5 × -5 - 30
→ Simplify
-25 - 30 = -55
If x - 10 = -15, then find the value of 5x - 30 the value of x is -55
