Y=3+2x / Y=-3x+13

Question

Use any method. Please show work. NEED HELP BADLY

Answer 1

Hi Jay

y = 7

x = 2

Thanks for your clarification above.

Given

y = 3 +2x

y = -3x + 13

Then you just set the representations of y equal to each other.

y = y

3 + 2x = -3x +13

Since

3 + 2x = -3x + 13 applies since they both represent y, then you just need to find x and continue from there. Thanks for your response above moving on

3 + 2x = -3x + 13

Get the variables on one side of the equation and the constants on the other

2x + 3x = 13 - 3

5x = 10

x = 2

Checking in the original equations

y = 3 + 2x= 3 + 2(2) = 3 + 4 = 7

and

y = -3x + 13

7 = -3(2) + 13

7 = -6 + 13

7 = 7

I hope this helps.
