Answer: the correct answer is b x=11
Step-by-step explanation:
2x - 3x + 3x = 5x + 30 + 3
2x = 5x + 33
( 2x - 5x = 5x + 33 - 5x
(1/3)-3x = 33x (1/3) Here we divide it but since it is 1/3, it is the same as dividing 3 divided by 11
1x = 11
x=11
<span>2x-4y=32
2x-8y=48
--------------subtract
4y = - 16
y = -4
</span>2x-4y=32
2x- 4(-4)=32
2x + 16 = 32
2x = 16
x = 8
answer
(8, -4)
Answer:
(3, 3 )
Step-by-step explanation:
Given the 2 equations
3x - y = 6 → (1)
6x + y = 21 → (2)
Adding the 2 equations term by term will eliminate y, that is
(6x + 3x) + (y - y) = (21 + 6), that is
9x = 27 (divide both sides by 9 )
x = 3
Substitute x = 3 into either (1) or (2) and solve for y
Using (2), then
(6 × 3) + y = 21
18 + y = 21 ( subtract 18 from both sides )
y = 3
Solution is (3, 3 )
The answer would be 6 (This is just to get 20 caracters NOT PART OF ANSWER)
