Find the solution of the equation on graphically 7r-15= r+27

r = 7

Step-by-step explanation:

let r = x

equation becomes

7x-15= x+27

Let the Left side AND Right side both equal y

y = 7x - 5

y = x + 27

graph these 2 equations. You should get 2 straight lines that intersect at x = 7, y = 34. (see attached)

recall at the start we let r = x, if we replace x with r again, we get r = 7

300

step-by-step explanation:

28-600w < 300

28-600w > 300

600-28w < 300

600-28w > 300
