What is 2(x + 8) = x + 21

x=5

Step-by-step explanation:

2(x + 8) = x + 21

Distribute

2x+16 = x+21

Subtract x from each side

2x-x +16 = x-x+21

x +16 = 21

Subtract 16 from each side

x+16-16 =21-16

x =5

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).
