Yes mate,
Hope you have a wonderful day
The answer to one is b. I recommend using a website called Desmos when you have to do things with equations. It has been very helpful to me and gives you the answer automatically. Even teachers recommend it.
Rearranging the first equation:-
3x - 4y = -7
9x + 4y = 139
12x = 132
x = 132/12 = 11
Substituting fro x in the second equation:-
9(11) + 4y = 139
4y = 139 - 99 = 40
y = 40/4 = 10
Answer x = 4 , y = 10.
Answer:
x= 5
Step-by-step explanation:
7x-14=2x+11
7x-2x= 11+14
5x= 25
x= 25/5= 5
hope it helps...please mark me brainliest
thank you!! have a good day ahead
