Question

For what value of x would these two equations have the same value? y = 45 + 20x y = 30 + 26x

Answer 1

Answer:

x=2.5 For both equations to be equal.

Step-by-step explanation:

45+20x=30+26x

Subtract 45 from each sides.

20x=-15+26x

Subtract 26x

-6x=-15

x=2.5

Check:

45+20(2.5)=30+26(2.5)

45+50=30+65

95=95 Correct!
