$\bf x-1.6=2.4+0.8x\implies \stackrel{\textit{subtracting 2.4}}{x-4=0.8x}\implies \stackrel{\textit{subtracting x}}{-4=0.8x-x} \\\\\\ -4=-0.2x\implies \cfrac{-4}{-0.2}=x\implies 20=x$

If < A and < B form a linear pair, and < A = x - 13 degrees, and < B = x + 7 degrees, then find x. Select one: a. 12

Andreas93 [3]

The correct value of "x" will be "93".

According to the question,

A linear pair of sum to 180°,

then

→ $x-13+x+7=180$

→ $2x -6=180$

By adding "6" both sides of the equation, we get

→ $2x-6+6=180-6$

→ $2x=186$

→ $x = \frac{186}{2}$

→ $x = 93$

Thus "option d" is the right answer.
