<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>
Answer:
15
Step-by-step explanation:
according to PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction) you would do 12 minus 6 first resulting in the answer of 6 so your equation would then be 5 x 6 divided by 2. 5 x 6 comes next in the equation and thats 30 so your new equation is 30 divided by 2. 30 divided by 2 is 15.
Answer:
A=15
