Answer: 5
Step-by-step explanation:
Is it supposed to say 7x rather than Z? If so then
If you make both equations = to 4y you can work out the answer so
4y =7x-4
4y = 36-3x
Then you put them equal to each other so
7x-4 = 36-3x
10x = 40
x = 4
You can then find y by doing
4y = 7x4 - 4
4y = 28-4
4y = 24
y= 6
So the answer is x = 4 and y = 6
1.) 11 + 11. Let's solve this in steps.
2.) 11 + 11 = 10 + 10 + 2
3.) 10 + 10 = 20
4.) 20 + 2 = 22
5.) 22 = answer
PEMDAS is order of operations...
Parentheses first, you can combine like terms...
8(6j+7)
Multiplication/division is next...8 times each term inside the parentheses
48j+56
Since there is one term with a variable and one is just a number that is as far as you can go...there are no more like terms...
