2(-3-7)+5= <span>2(-10)+5= -20 + 5= -15
-15 is your final answer</span>
Answer: i would say 60 cm sorry if im wrong i think your missing a number
Step-by-step explanation:
An ordered pair (x,y) is a solution to a system of equations if it makes all the equations true.
Let's check whether (–1, 5) makes the equations true.
Plugging –1 in the first equation for x and 5 in for y, we get
–1 + 5 = 4: TRUE
Plugging –1 in the second equation for x and 5 in for y, we get
–1 – 5 = –6: TRUE
Since it makes both the equations true, it's a solution to the system of equations. So the answer choice is D, the 4th one.
