Question

How do i solve this

Answer 1

Replace g for -2 and h for 5.

(2(-2) + 9(5) -5) - (6(-2) - 4(5) +2)

Taking this one at a time,
2(-2) = -4, and 9(5) = 45.
6(-2) = -12 and -4(5) = -20

(-4 + 45 - 5) - (- 12 - 20 +2)

Let’s distribute the negative symbol to the right side.

(-4 + 45 - 5) + (12 + 20 - 2)

Then, we solve!
(-4 + 40) + (12 + 18)

(36) + (30)

= 66!

Answer 2

Answer:

64

Step-by-step explanation:

Okay, here it goes:

Where there is a g you insert -2 and where there is an h you insert 5

(2(-2)+9(5)-5)-(6(-2)-4(5)+2)

If two numbers are side-by-side with no other sign between them, you multiply

(-4+45-5)-(6(-2)-4(5)+2)

(-4+45-5)-(-12-20+4)

There is a subtraction sign between these equations. That means you must distribute the negative sign to the equation on the right.

Remember:

• Negative × Negative = Positive
• Negative × Positive = Negative
• Positive × Positive = Positive

-4+45-5+12+20-4

Now just add them together. I recommend going left to right.

-4+45=41

41-5=36

36+12=48

48+20=68

68-4=64
