Plug in y=3x+2 into the y in the second equation.
x + 2(3x+2) = 11
x + 6x + 4 = 11
7x + 4 = 11
7x = 7
x = 1
then, plug the x value into x in the first equation.
y = 3(1) + 2
y = 3 +2
y = 5
Answer:
f x d = d x f
The commutative property of multiplication is just the numbers switched around, but it doesn't change the product. It has to in multiplication.
Assuming that the angles are congruent, then y = 29.
4y - 8 = 79 + y
4y = 87 + y Add 8 to both sides
3y = 87 Subtract y from both sides
y = 29
The answer is 32,768. Do the problem same as your example.
