y=-3+5 and y=4x-2

Answer: Put other y in the other equation

so u got: 4x-2=-3+5

4x-2=2

4x =4

x =1

Now put x in the equation

so u do like this: y=4(1)-2

y=2

solution is (1,2) good luck

so u got: 4x-2=-3+5

4x-2=2

4x =4

x =1

Now put x in the equation

so u do like this: y=4(1)-2

y=2

solution is (1,2) good luck

What is 4/5 - 3/4?????

Well first you have to find a common denominator. 5 and four, their least common denominator is 20 so make the denominator 20.

4/5 = 16/20

3/4 = 15/20

16/20 - 15/20 = 1/20

4/5 = 16/20

3/4 = 15/20

16/20 - 15/20 = 1/20

is your final answer.
