Answer:
(2x+5)in x 3 in =51 in^2
Step-by-step explanation:
First, divide both sides by 3: (2x+5)/3 = 51/3-->2x+5=17
Then, subtract both sides by 5: 2x+5-5 = 17-5-->2x=12
Finally, divide both sides by 2: 2x/2 = 12/2 -->x=6
So, the answer is x=6.
Good luck and I hope this helps!
Answer:
Step-by-step explanation:
1/3 + 1/3= 2/3
5/10-2/10=3/10
4/5-2/5=2/5
11+1=12
They are equal, 85 divided by 100 is 0.85
Multiply one of them by -1 so one of the -2y is positive
-1(-7x-2y=-13)=7x+2y=13
Then add the two equations
7x+2y=13
+ x-2y=11
========
8x=24 - the 2y and -2y cancel out. Now solve for x
x=3 Now plug the x back into one of the equations
3-2y=11 Now solve for y
-2y=11-3
-2y=8
y=-4
So x=3 and y=-4
Hope this helps!
