(5a).7 = -23 7(5a) = -23 35a = -23 a = -23/35 a= -0.657 (3 d.p.)

Yes, because: x+7 = 23 x = 23-7 x = 16

5x - 7 = 23 .....+7....+7 5x=30 --- --- 5.....5 --->(x=6)<---
(5a).7 = -23 7(5a) = -23 35a = -23 a = -23/35 a= -0.657 (3 d.p.)

No it equals 21
23 divided by 3 equals 7 with a remainder of 2.
7.6667
s = 7, t = -3
Yes, because: x+7 = 23 x = 23-7 x = 16
Well, isn't that a happy little math problem! If we take 23 and divide it by 7, we find that 7 goes into 23 three times. Just imagine those little sevens peacefully fitting into the number 23, creating a lovely harmony of numbers. Math is just like painting, it's all about finding the right balance and enjoying the process.
-23+7=-16
let's solve this problem:-the first step; (find the 'y')8y-7 = 23 -2y8y+2y = 23+710y = 30y = 30:10y = 3-the second step; (change the 'y' with '3')8(3) -7 = 23 -2(3)24 -7 = 23 -617 = 17well, The conclusion and the answer is;8y -7 = 23 - 2y --> is True Equal ;)
