Step-by-step explanation:

This is a right triangle with two congruent angles. so this is a isoceles right triangle or called a

45-45-90 triangle. This means that the legs are equal to each other so

$3(x + 2) = 24$

$3x + 6 = 24$

$3x = 18$

$x = 6$

vladimir1956 [14]

Answer:

Step-by-step explanation:

$\left\{\begin{array}{ccc}x=3y&\text{subtract}\ 3y\ \text{from both sides}\\3x-2y=14\end{array}\right\\\\\left\{\begin{array}{ccc}x-3y=0&\text{multiply both sides by (-3)}\\3x-2y=14\end{array}\right\\\underline{+\left\{\begin{array}{ccc}-3x+9y=0\\3x-2y=14\end{array}\right}\qquad\text{add both sides of the equations}\\.\qquad\qquad7y=14\qquad\text{divide both sides by 7}\\.\qquad\qquad y=2\\\\\text{put the value of y to the first equation:}\\x=3(2)=6$

Plz help need step by step

Xelga [282]

Answer: X would equal -7

Step-by-step explanation: First off, we cross multiply. So 374/(x-10) = -22/1 would be: 374 = -22(x-10). We then get 374 = -22x +220. You would subtract 220 from both sides then divide by -22 to get x. You could then substitute -7 in for x, to check your answer.
