3x+4y =-5 3x+3y=-2 solve using substitution

galben [10]

3x + 4y = -5
-3x -3x

4y= -3x -5
/4 /4

y= -3/4x-5/4

3x + 3y = -2
-3x -3x

3y = -3x-2
/3 /3

y= -1x-2/3

ST= Help me please thank u

dmitriy555 [2]

Step-by-step explanation:

RS + ST = 8

(RS + ST)×RS = (4 + 2)×4

8 × RS = (4 + 2) × 4 = 6 × 4 = 24

RS = 24/8 = 3

RS + ST = 8

3 + ST = 8

ST = 5

Express the product in simplest form.

Dmitry [639]

The product in simplest form is (x - 4)

Solution:

Given expression is:

$\frac{8}{2x+8} \times \frac{x^2-16}{4}$

We have to find the product in simplest form

In the given expression,

2x + 8 = 2(x+ 4)

We know that,

$a^2-b^2=(a+b)(a-b)$

Therefore,

$x^2-16 = x^2-4^2 =(x+4)(x-4)$

Substitute these in given expression

$\frac{8}{2(x+4)} \times \frac{(x+4)(x-4)}{4}$

Cancel the common factors,

$\frac{8}{2(x+4)} \times \frac{(x+4)(x-4)}{4} = x - 4$

Thus the product in simplest form is (x - 4)
