Answer 2

Let's solve each equation step by step:

A) 4.9X - 6.7 = -6.9X - 10.9

To solve this equation, we'll start by combining like terms on each side:

4.9X + 6.9X = -10.9 + 6.7

11.8X = -4.2

Next, we'll isolate X by dividing both sides of the equation by 11.8:

X = -4.2 / 11.8

Simplifying the division:

X ≈ -0.356

Therefore, the solution to the equation A) is X ≈ -0.356.

B) 3(2x - 4) = -5(3x + 2)

Let's distribute the multiplication on both sides:

6x - 12 = -15x - 10

Now, we'll collect the variables on one side and the constants on the other side:

6x + 15x = -10 + 12

21x = 2

Dividing both sides by 21:

x = 2 / 21

Simplifying the division:

x ≈ 0.095

Therefore, the solution to equation B) is x ≈ 0.095.
