$25 - ({a + 7})^{2} =$

$(5 + (a + 7))(5 - (a + 7)) =$

$(a + 12)( - a - 2)$

How to solve equation an equation without y using elimination method

Sedbober [7]

Work only with the second equation at the beginning. Solve for x for it.

7x - 2x = 3 Combine the left hand side.

5x = 3 Divide by 5

5x/5 = 3/5 Do the division

x = 3/5 = 0.6

==============

Now work with the top equation.

3(0.6) + 5y = 13 Multiply on the left.

1.8 + 5y = 13 Subtract 1.8 from both sides.

1.8 - 1.8 + 5y = 13 - 1.8 Do the subtraction

5y = 11.2 Divide by 5

5y/5 = 11.2/5

y = 2.24 Answer

butalik [34]

Answer:

$(a)\ t =\frac{d}{v}$

$(b)\ d = vt$

Step-by-step explanation:

The question is mixed up with details of another question. See comment for original question

Given

$v = \frac{d}{t}$

$v \to velocity$

$d \to distance$

$t \to time$

Solving (a): Solve for time

We have:

$v = \frac{d}{t}$

Cross multiply

$t * v = d$

Make t the subject

$t =\frac{d}{v}$

Solving (b): Solve for distance

We have:

$v = \frac{d}{t}$

Cross multiply

$d = v * t$

$d = vt$
