Solve the top equation to get on variable on one side
2x-y=6
-y=-2x+6
y=2x-6
then plug in the coordinate for x and y for both equations. if both equations are true then it’s a solution
2=2(2)+6
2=10

4+2=6

so it’s not a solution

Solve for y. 2 (y-2) = 4y + 8 - 2 (-4y - 3)

Lubov Fominskaja [6]

Answer:

-1.5

Step-by-step explanation:

2 (y-2) = 4y + 8 - 2 (-4y - 3)
2y-4=4y+8+8y+6
2y-4=12y+14
-4-14=14y-2y
-18=12y
y=-18/12
y=-1.5

Solve the following equation. Round solution to the tenths place. 29 = с/7.2 C =

expeople1 [14]

Answer:

c = 208.8

Step-by-step explanation:

a. $\frac{c}{7.2} =29$ To solve for C, you need to get the variable on one side of the equation and the numbers on the other side of the equation.

b. $\frac{c}{7.2} =29$ You need to move the 7.2 to the other side. So, multiply both sides by 7.2, because it's being divided, so multiplying will cancel it out.

c: $c = 29 * 7.2$ Then, multiply 7.2 by 29. (The * symbol means multiply)

d. c. = 208.8 The answer is 208.8, which is rounded to the tenths place.

Hope this helps! I tried to explain it in detail. :)
