Step-by-step explanation:
12x-4x=37-5
8x=32
x=32/8
x=4
Well we know that 18 is 3/5 of 30, so all you have to do is add another zero to your thirty and with doing that you can add a zero to 18. So your final answer is 180!
Answer:
y= 1
Step-by-step explanation:
This is because there will be no increase or decrease of x since we have no slope to take us there so it will remain constant at the y value

4a-5b=7; 4a+5b=17
Solve for a and then solve for b or either or of the variable
4a-5b=7
4a=7+5b
A=(7+5b)/4 then plug into a for 4a+5b=17
4((7+5b)/4)+5b=17
7+5b+5b=17
7+10b=17
10b=17-7
10b=10
B=1 then plug into solved a=(7+5b)/4
A=(7+5(1))/4
A=(7+5)/4
A=12/4
A=3
A=3;b=1
