Step-by-step explanation:
x+3y=24
3y/3=24/3
x+y=8
divide x to both side not to y
y=-x +8
Answer:
x=15 y=22.5
Step-by-step explanation:
6x-5=85
6x=90
x=15
4y=90
y=22.5
4y makes a right angle so it is 90 degrees
X in the equation 2/X+1/2=3/4 equals 8
We can find this by first finding the common denominator of 1/2 and 3/4 which is 2/4.
Then we can ask, 2/4+?=3/4
By asking this question we can find out that 2/4+1/4=3/4
With this new knowledge we can now ask 2/?=1/4. Which will lead us to the answer 8.
