Add -2x to both sides to get 'x' on one side of the equation
-2x-3=4x-15
+2x   +2x
__________
-3=6x-15

add 15 to both sides to isolate 6x
-3=6x-15
+15=6x+15
__________
12=6x

divide both sides by 6 to get 'x' alone
12=6x
/6=/6
_____
2=x

so your answer is 2=x or you can flip it and it will be the same, x=2

DanielleElmas [232]

Answer:

The price of a single printer cartridge is 19.69, in your given currency.

Step-by-step explanation:

First remove the tax and the software package from the total bill.

90.01 - 24.99 - 5.95 = 59.07

Since there are 3 cartridges, you divide 59.07 by 3, giving you the price of a single cartridge.

59.07 \div 3 = 19.69

Can someone help with this problem please? Thanks.

First, find the slope of the line. Use the two points given, (-4,0) and (4,2), in the slope formula rise over run. The change in rise is 2 and the change in run is 8, meaning that the slope is 2/8, simplified to 1/4. The y-intercept is 1, shown by the graph and the dashed line and shaded area means that the inequality symbol must be <. Slope-intercept form is shown as y = mx + b, so after putting our information in to the equation the answer is y < 1/4x + 1. Hope this helps!
