Question

Solve 1.2(5-x) = 2(1.4x+3)

Answer 1

Answer:

x = 0

Step-by-step explanation:

Solve for x:

1.2 (5 - x) = 2 (1.4 x + 3)

Expand out terms of the left hand side:

6 - 1.2 x = 2 (1.4 x + 3)

Expand out terms of the right hand side:

6 - 1.2 x = 2.8 x + 6

Subtract 2.8 x from both sides:

6 + (-1.2 x - 2.8 x) = (2.8 x - 2.8 x) + 6

-1.2 x - 2.8 x = -4 x:

-4 x + 6 = (2.8 x - 2.8 x) + 6

2.8 x - 2.8 x = 0:

6 - 4 x = 6

Subtract 6 from both sides:

(6 - 6) - 4 x = 6 - 6

6 - 6 = 0:

-4 x = 6 - 6

6 - 6 = 0:

-4 x = 0

Divide both sides of -4 x = 0 by -4:

(-4 x)/(-4) = 0/(-4)

(-4)/(-4) = 1:

x = 0/(-4)

0/(-4) = 0:

Answer:  x = 0
