Let's solve each equation separately:

5(0.3x + 6) - 4(0.2x - 7) = -5

Distribute the numbers in the parentheses:
1.5x + 30 - 0.8x + 28 = -5Combine like terms:
0.7x + 58 = -5Subtract 58 from both sides:
0.7x = -63Divide by 0.7:
x = -90

0.5(3x - 4) + 6 + 4.4 = 0.9(4x - 2)

Distribute the numbers in the parentheses:
1.5x - 2.0 + 6 + 4.4 = 3.6x - 1.8Combine like terms:
1.5x + 8.4 = 3.6x - 1.8Subtract 1.5x from both sides:
8.4 = 2.1x - 1.8Add 1.8 to both sides:
10.2 = 2.1xDivide by 2.1:
x = 4.857142857142857 (approximately 4.86)
