Answer: 15
Step-by-step explanation: To evaluate an expression, we plug the value of the variable into the expression and simplify.
Since we have 7 - 2x and x is -4, we have 7 - 2(-4).
Simplifying from here, 2(-4) is -8 so we have 7 - (-8).
Now, remember that a a minus sign followed by a
negative sign turns the two signs into a plus sign.
So 7 - (-8) can be thought of as 7 + (+8) which is 15.
Answer:
-4
Step-by-step explanation:
Divide each side by '-1'.
p = -4
Simplifying
p = -4
Subtract the 18 from the 78 then multiply both sides by -1, then divide by 5.
