Answer:

B. (4, 28)

Step-by-step explanation:

y=8x-4

x=4

Let x = 4 in the first equation:

y = 8(4) - 4

y = 32 - 4

y = 28

x = 4; y = 28

Solve the equation for x.<br> 1/3 (6x - 15) = 1/2 (10x-4)
Readme [11.4K]

Answer:

<h2>x = - 1</h2>

Step-by-step explanation:

\frac{1}{3} (6x - 15) =  \frac{1}{2} (10x - 4)

Expand the terms in the bracket

That's

\frac{1 }{3}  \times 6x  +   \frac{1}{3} ( - 15) =  \frac{1}{2} (10x)   +  \frac{1}{2} ( - 4) \\ 2x - 5 = 5x - 2

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

2x  - 5x - 5 = 5x - 5x - 2  \\  - 3x - 5 =  - 2

<u>Add 5 to both sides</u>

- 3x - 5 + 5 =  - 2 + 5 \\  - 3x = 3

<u>Divide both sides by - 3</u>

\frac{ - 3x}{ - 3}  =  \frac{3}{ - 3}

We have the final answer as

<h3>x = - 1</h3>

Hope this helps you
