Problem 1 Answer: x=10

<u>Simplify both sides of the equation</u>

<u></u>(2)(x)+(2)(-3)=14(Distribute)<u></u>

<u></u>2x+-6=14<u></u>

<u></u>2x-6=14<u></u>

<u></u>

<u>Add 6 to both sides</u>

2x-6+6=14+6

2x=20

<u></u>

<u>Divide both sides by 2</u>

<u></u>2x/2=20/2<u></u>

<u></u>x=10<u></u>

----------------------------------------------------------------

Problem 2 Answer: x=-7

<u></u>

<u>Simplify both sides of the equation</u>

<u></u>(-5)(x)+(-5)(-1)=40(Distribute)<u></u>

<u></u>-5x+5=40<u></u>

<u></u>

<u>Subtract 5 from both sides</u>

<u></u>-5x+5-5=40-5<u></u>

<u></u>-5x=35<u></u>

<u></u>

<u>Divide both sides by -5</u>

<u></u>-5x/5=35/-5<u></u>

<u></u>x=-7<u></u>

----------------------------------------------------------------

Problem 3 Answer: x=-8

<u></u>

<u>Simplify both sides of the equation</u>

<u></u>(12)(x)+(12)(10)=24(Distribute)<u></u>

<u></u>12x+120=24<u></u>

<u></u>

<u>Subtract 120 from both sides</u>

<u></u>12x+120-120=24-120<u></u>

<u></u>12x=-96<u></u>

<u></u>

<u>Divide both sides by 12</u>

<u></u>12x/12=-96/12<u></u>

<u></u>x=-8<u></u>

----------------------------------------------------------------

Problem 4 Answer: x=-1/2

<u></u>

<u>Move all terms to the left:</u>

<u></u>2(x+6)-(11)=0<u></u>

<u></u>

<u>Multiply parentheses</u>

<u></u>2x+12-11=0<u></u>

<u></u>

<u>Add all the numbers together, and all the variables</u>

<u></u>2x+1=0<u></u>

<u></u>

<u>Move all terms containing x to the left, all other terms to the right</u>

<u></u>2x=-1\\x=-1/2<u></u>

----------------------------------------------------------------

Wat is the value of x in the equation<br>5x + 2(x + 1) = 4​
PIT_PIT [208]

Answer:

x = \bf~\frac{2}{7}~or~0,285

Step-by-step explanation:

5x + 2(x + 1) = 4

5x + 2x + 2 = 4 (here we got rid of the parenthesis)

7x + 2 = 4 (here we summed both of our x values)

7x = 4 - 2 (here we took #2 to the other side of the equation)

7x = 2 (we subtracted 4 - 2)

x = 2 / 7

x = \bf~\frac{2}{7}~or~0,285

Does 4=-3/2(-4)-2 equal out to (-4,4)
Marizza181 [45]

Answer:

yes

Step-by-step explanation:

well im going to assume that the original equation is y = -3/2x - 2

if that is the case, then if you plug in the numbers

4 = -3/2(-4) - 2

4 = 6 - 2

4 = 4

so yes when x is -4, y is 4; (x, y) (-4, 4)

How do you factor 8y^3+316
PilotLPTM [1.2K]
8y^3+316
divide both sides by 4 (smallest divisable number) just say you tried to factor 2 and 3 and they weren't whole numbers and then you tried 4 and gave you the answer :)
4(2y^3+79)

Please help will mark brainliest
Butoxors [25]
4, 16
-1, 1
3, 9
12, 144
16, 256

The rule is y=x^2. If you square all the numbers on the x side, you will get the numbers on the y side. 4 times 4 = 16. -1 times -1 =1. 3 times 3 =9, and so on.
