The first step in this equation is to Subtract 18 from both sides of the equation.
depending on how many green and purple there are, lets say 4, and there are 10 other colors, it would be 4/10 so its 40%
Answer:
The answer is 2
Step-by-step explanation:
When a line is parallel to the other line, they must have the same gradient.
<span>2x+ y = 3
x = 2y - 1
Make sure there are NO SPACES in your answer. Include a comma in your answer.
It looks like I could substitute the x=2y-1. Into 2x+y=3
2(2y-1)+y=3
4y-2+y=3
5y=5
y=1
x=2(1)-1
x=1
(1,1)
CHECK
2x+y=3
2(1)+(1)=3
2+1=3
3=3
Left hand side=Right hand side
Check other equation
x=2y-1
1=2(1)-1
1=1
Therefore the solution is (1,1). Since the left hand side= right hand side in each equation</span>
