Answer:
Subtraction property of equality.
At very minimum, move (4/5)x to the other side of the given equation. Then:
-(4/5)x + y = 0.85. This is the equation in standard form.
V = (4/3)×3.14×(1.5^3)
V = 14.1 in^3
Answer:
x=2,y=2
Step-by-step explanation:
This question is a simultaneous equation
So let's solve
3x+y=8...(1)
2x+2y=8....(2)
Multiply (1) by 2
6x+2y=16...(3)
Substrate (2) From (3)
4x=8
Let's make x the subject of formula by dividing both sides by 4
x=2
So let's substitute the value of x into (1)
3x+y=8
3(2)+y=8
6+y=8
y=8-6
y=2
Therefore x is 2,y is 2
