Solve the following system of equations. 2x + y = 3 x = 2y - 1 Make sure there are NO SPACES in your answer. Include a comma in
Natalka [10]
2x + y = 3
x = 2y - 1

solve for y in the first equation;
2x + y = 3
y = 3 - 2x 

x = 2y - 1
x = 2(3 - 2x) - 1
x = -4x + 5

solve for x;
x = -4x + 5
x + 4x = 5
5x = 5
x = 1

solve for y;
y = 3 - 2x
y = 3 - 2(1)
y = 1

the answer is: x = 1, y = 1

hope this helps, God bless!

Helen ate 1/10 of a cake. She divided The remainder into 3 equal portions. What fraction of the cake was in each portion
Vlad1618 [11]

Answer:

As she ate 1/10 of cake, we need to know how many cake remains after it, so we can substract:

1 - 1/10 = 10/10 - 1/10 = 9/10

Then, we need to divide the 9/10 into 3 portions:

(9/10) / 3 = 9/30 = 3/10

So we know the fractions would be 3/10 each on this situation..
