Answer:

f/2 = -20

f = -10

Step-by-step explanation:

1. Subtract 9 on both sides

f/2 + 9 -9 = 4 -9

= f/2 = -5

2. Multiply all terms by the same value to eliminate fraction denominators

2* f/2 = 2(-5)

3. Simplify

f = -10

Solve 3x − 2y = −21 and 2x + 5y = 5 using elimination
nydimaria [60]

Answer:

x = -5 and y = 3

Step-by-step explanation:

There are two equations :

3x − 2y = −21 ....(1)

2x + 5y = 5 ......(2)

Multiply equation (1) by 2 and equation (2) by 3.

6x - 4y = -42 ...(3)

6x + 15y = 15 ....(4)

Subtract equation (4) from (3) :

6x - 4y - (6x + 15y) = -42 -15

-4y -15y = -57

-19y = -57

y = 3

Put y = 3 in equation (2) :

2x + 5(3) = 5

2x = 5-15

2x = -10

x = -5

So, the value of x is (-5) and y = 3.
