4x -2y = 60
4x -3y = 26
(-) (+) (-)
__________
1y = 34
y = 34

To find x
4x -2y = 60
4x -(2)(34) = 60
4x -68 = 60
4x = 60 + 68
4x = 128
x = 32

Answer:

Step-by-step explanation:

4x - 2y = 60

4x - 3y = 26.....multiply by -1

-----------------------

4x - 2y = 60

-4x + 3y = -26 (result of multiplying by -1)

-----------------------add

y = 34

4x - 2y = 60

4x - 2(34) = 60

4x - 68 = 60

4x = 60 + 68

4x = 128

x = 128/4

x = 32

check...

4x - 3y = 26

4(32) - 3(34) = 26

128 - 102 = 26

26 = 26 (correct)

so x = 32 and y = 34.....or (32,34)

MULTIPLE CHOICE 9th grade math: help me find the formula to the nth term:
maxonik [38]

Answer:

a_{n} = - 5n - 2

Step-by-step explanation:

There is a common difference between consecutive terms, that is

- 12 - (- 7) = - 17 - (- 12) = - 5

This indicates the sequence is arithmetic with n th term

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 7 and d = - 5, then

a_{n} = - 7 - 5(n - 1) = - 7 - 5n + 5 = - 5n - 2
