7.8+2(0.75m+0.4)=-6.4m+4(0.5m-0.8)

7.8 + 2 (0.75 m + 0.4) = - 6.4 m + 4 (0.5 m - 0.8)

m = - 2

Solution steps

7.8 + 2 (0.75 m + 0.4) = - 6.4 m + 4 (0.5 m - 0.8)

Expand

4 (0.5 m - 0.8) : 2 m - 3.2

1.5 m + 8.6 = - 6.4 m + 2 m - 3.2

Add similar elements:

- 6.4 m + 2 m = - 4.4 m

1.5 m + 8.6 = - 4.4 m - 3.2

Expand

7.8 + 2 (0.75 m + 0.4) : 1.5 m + 8.6

1.5 m + 8.6 = - 4.4 m - 3.2

Move

8.6

to the right side

1.5 m = - 4.4 m - 11.8

Move

4.4 m

to the left side

5.9 m = - 11.8

Divide both sides by

5.9

m = - 2

x, \frac{x}{2} - \frac{y}{3} = \frac{1}{6} + y

x, x + y + 2 z = 4

(5^{2} + 2^{3}) \cdot x + 4^{2} = 7^{2}

a, 7 a + 5 b = 49

x, g = 2 f - 2
