Answer:

8

Step-by-step explanation:

(6x + 2) + 40 = 90 because the entire angle is a right angle, therefore the whole angle is 90

subtract 40 from each side: 6x + 2 = 50

now subtract 2 from each side: 6x = 48

now divide 6 from each side: x = 8

amm1812

Answer:

x = -34.8

Step-by-step explanation:

<h2><u>solve the equation</u></h2>

2(x-3)

= 2x - 6

7(x + 24 )

= 7x + 168

put the equation together

2x - 6 = 7x + 168

now make x subject of formula:

2x - 7x = 168 +6

-5x = 174

x = 174/ -5

<h3><u>x = -34.8 </u></h3>
