Answer:

{-2/7, 2/7}

Step-by-step explanation:

Here you're being asked to solve the given equation 49w^2-4=0 for w with the hint that the solutions are fractions.

49w^2-4=0 is the product of the sum and difference of two squares:

(7w - 2)(7w + 2) = 0

Setting each factor equal to zero and solving for w, we get:

{-2/7, 2/7} as the solutions.

Solve using substitution:<br> 2x - 3y = -1<br> y = x - 1
denis-greek [22]

<em>Answer:</em>

<em>x=4 y=3</em>

<em>Step-by-step explanation:</em>

<em>rewrite the equations- y=x-1 2x-3y=-1</em>

<em>solve y=x-1 for y</em>

<em>y=x-1</em>

<em>sub for x-1 for y in 2x-3y=-1</em>

<em>2x-3y=-1</em>

<em>2x-3(x-1)=-1</em>

<em>-x+3=-1</em>

<em>-x+3+-3=-1+-3</em>

<em>-x=-4</em>

<em>divide both sides by -4</em>

<em>x=4</em>

<em>sub 4 for x in y=x-1</em>

<em>y=x-1</em>

<em>y=4-1</em>

<em>y=3</em>

<em>WE ARE VENOM</em>

Answer:

Step-by-step explanation:

suppose the first one is x. so the other one should be 6x-94 (as said).

so : x+6x-94 = 956 . then 7x -94 = 956 . then 7x = 1050 . so x = 1050/7 . then        

x = 150
