Answer:
x = 23
7x - 11 = 4x + 58
(7x - 4x) - 11 = (4x - 4x) + 58
3x - 11 = 58
3x (- 11 + 11) = 58 + 11
3x = 69
3x/3 = 69/3
x = 23
2/3 * 9/20 = 18/60
= 9/30
= 3/10

Equation at the end of step 1 :
6x • (4 + 2)
Step 2 :
Final result :
36x
Substitute in what you already know into the formula, since the formula is (a=bh) you already know what A is so now you have 50=bh, now the length is x+7 , length is basically height , so h in the formula , so now you get 50=b(x+7) , now you need b luckily you already have b, so plug in 50=(x+2)(x+7) , you can guess and check or you can solve for x by double distributing
