:two numbers sum to 65 twice the first subtracted from the second is 5 find the numbers

a+b = 65

b - 2a = 5

Solve one variable in terms of another:

b = 5 + 2a

Substitute in this variable:

a + 5 + 2a = 65

3a = 70

a = 23.3

Use this to find the other variable:

23.3 + b = 65

b = 41.7

Check the

23.3 + 41.7 = 65

65 = 65

ANSWERS:

a = 23.3

b = 41.7

b

step-by-step explanation:

u take $75 minus $60.the anwer/original($75)multiply by 100

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
