<u>Given</u><u> equation</u><u> </u>is {(3x+1)/5} = {(2x-2)/6}

On applying cross multiplication then

⇛6(3x+1) = 5(2x-2)

Multiply the numbers outside the bracket with numbers in bracket.

⇛18x + 6 = 10x - 10

Shift the variable value on LHS and the constant value on RHS.

⇛18x - 10x = -6-10

Subtract the values on LHS and RHS.

⇛8x = -16

Shift the value 8 from LHS to RHS.

⇛x = -16÷8 = -16/8

⇛x = -2

Therefore, x = -2

<u>Answer</u><u>:</u> Hence, the value of x for the given problem is -2

Please let me know if you have any other questions.

Answer:

<h2>cross multiplication</h2>

6(3x + 1) = 5(2x - 2) \\ 18x + 6 = 10x - 10 \\ 18x - 10x =  - 10 - 6 \\ 8x =  - 16 \\ x =  \frac{ - 16}{8}  \\ x =  - 2

<h2>hope it helps you<3</h2>

What’s the slope and y-intercept for 2y+5x-8=0
IrinaVladis [17]

Answer:

<u>Slope</u>- -5/2 <u>Y Int.</u>- 4

Step-by-step explanation:

You would first need rto put the equation in slope intercept form by subtracting -5x and adding 8 to both sides the you will divide two from each #. Then your equation will be in slope intercpt form which allows you identyify 4 as the y intercpt and -5/2x as the slope.

2y+5x-8=0

    -5x +8      -5x   + 8 = 2y=-5x+8

2y/2=-5x/2+8/2

y=-5/2x+4

Select the correct answer.<br> Rewrite the following equation as a function of x.
ivolga24 [154]

Option B:

${f(x)}=9280-20x

Solution:

$\frac{1}{16} x+\frac{1}{320} y-29=0

$\frac{1}{16} x+\frac{1}{320} y-\frac{29}{1} =0

Take LCM of the denominators and Make the denominators same.

LCM of 16, 320, 1 = 320

$\frac{1\times20}{16\times20} x+\frac{1}{320} y-\frac{29\times 320}{1\times 320} =0

$\frac{20}{320} x+\frac{1}{320} y-\frac{9280}{320} =0

All the denominators are same, so you can write in one fraction.

$\frac{20x+y-9280}{320}=0

Do cross multiplication.

${20x+y-9280}=0\times 320

${20x+y-9280}=0

Add 9280 on both sides of the equation.

${20x+y}=9280

Subtract 20x on both sides of the equation.

${y}=9280-20x

Let y = f(x).

${f(x)}=9280-20x

Hence Option B is the correct answer.
