It's a linear equation in 'x'.To solve it:x + 19 = 42Subtract 19 from each side of the equation:x = 23
19 + 19 + 4 + 4 = 46

Negative 23 + 32 minus 18 = negative 9 {-23+32-18=-9)
s = 7, t = -3
Oh, dude, if 5 plus n equals 23, then n must be 18, right? So, if you wanna find out what n minus 5 equals, just subtract 5 from 18 and you get 13. Easy peasy lemon squeezy.
19 + (44 + 23) = (19 + 44) + 23
3x + 5 = 6x + 23 -3x = 18 x = -6
18 + 23 + 23 = 64
