Answer:
2/3, 12/18 and 18/27
Step-by-step explanation:
Answer:
x = 5
y = 1
Step-by-step explanation:
So move 2y from the second equation to the other side of the equals sign
2x +3y = 13
x = 3 + 2y
From here substitute X into the first equation
2(3 + 2y) + 3y = 13
Distribute
6 + 4y +3y = 13
Combine like terms and solve for y
7y = 7
y = 1
insert result into the original equation.
x-2(1) = 3
x - 2 = 3
x = 5
insert into other equation to check work
2(5) + 3(1) = 13
10 + 3 = 13 correct

Answer: 81
Right Hand: Simplify the following:
3 (25 + 2)
Hint: | Evaluate 25 + 2.
25 + 2 = 27:
3×27
Hint: | Multiply 3 and 27 together.
3×27 = 81:
