Final answer:

To solve for x, isolate the variable on one side of the equation by performing inverse operations. For the first equation, divide by 75° and then solve for x. For the second equation, divide by 649 and then solve for x.

Step-by-step explanation:

To solve for x in the given equations, we need to isolate x on one side of the equation.

Equation 1:

75°(2x - 5) = 13

Divide both sides of the equation by 75° to isolate the expression (2x - 5):

2x - 5 = 13/75°

Add 5 to both sides of the equation:

2x = 13/75° + 5

Convert 13/75° to decimal form, then simplify:

2x = 0.1733 + 5

2x = 5.1733

Divide both sides of the equation by 2 to solve for x:

x = 2.5867

Equation 2:

649(48 + x) = 14

Divide both sides of the equation by 649 to isolate the expression (48 + x):

48 + x = 14/649

Subtract 48 from both sides of the equation:

x = 14/649 - 48

Convert 14/649 to decimal form, then simplify:

x = 0.0216 - 48

x = -47.9784
