Can someone help me solve 5(t+2) please
Answers
Answer 1
Answer:
This is a simple multiplication, written in a strange form.
5(t+2) means 5 x t + 5 x 2 which simplifies to:
5t + 10
If it's equal to a number, 0 for example, then with a little rearranging we can find what t is.
5t + 10 = 0,
5t = -10
t = -2
If it's not equal to something, the answer is just 5t + 10.
5(t+2) means 5 x t + 5 x 2 which simplifies to:

If it's equal to a number, 0 for example, then with a little rearranging we can find what t is.
5t + 10 = 0,
5t = -10
t = -2
If it's not equal to something, the answer is just 5t + 10.

3x + 2y = 14....multiply by 2
2x - 4y = 4
----------------
6x + 4y = 28 (result of multiplying by 2)
2x - 4y = 4
----------------add
8x = 32
x = 32/8
x = 4
2x - 4y = 4
2(4) - 4y = 4
8 - 4y = 4
-4y = 4 - 8
-4y = -4
y = -4/-4
y = 1
solution is (4,1)
