Yeah cuz u could +1 to each side of the second equation to get rid of both the -1’s and that is equivalent to the first equation :)

Intersecting Secant (Exterior) Find X =

levacccp [35]

Answer: x = 13

Step-by-step explanation: the equation to solve this is:

4 × (4 + 8) = 3 × (3 + x)

so we solve the first half of that:

4 × (4 + 8)

4 × 12

now we have:

48 = 3 × (3 + x)

so we switch the sides to make it easier and solve

3 × (3 + x) = 48

divide both sides by 3

3 × (3 + x) ÷ 3 = 48 ÷ 3

and get

3 + x = 16

now subtract 3 from both sides

3 + x = 16

-3 -3

and finally we get

x = 13

hope this helped :)

1 1/2= v + 3/4 (that's 1 and a half, not 11 over 2) what is v?

Irina-Kira [14]

Answer:

The value of v is 3/4.

Step-by-step explanation:

First, you have to convert mixed number into improper fraction :

$1 \frac{1}{2} \\ = \frac{2 \times 1 + 1}{2} \\ = \frac{3}{2}$

In order to find the value of v, you have to substract 3/4 to both sides :

$\frac{3}{2} = v + \frac{3}{4}$

$\frac{3}{2} - \frac{3}{4} = v + \frac{3}{4} - \frac{3}{4}$

$v = \frac{3 \times 2}{2 \times 2} - \frac{3}{4}$

$v = \frac{6}{4} - \frac{3}{4}$

$v = \frac{3}{4}$

Solve the system of linear equations by elimination. 9x−2y=349x−2y=34 5x+2y=−6

stealth61 [152]

So combine all the x and the Y on the left side and the coefficients on the right and then multiply the variable (x or Y) by the number needed for both. and then whichever variable you have left (x or y) will equal the coefficient and then divide by the coefficient
