Answer:
x=17
Step-by-step explanation:
53+(2x+3)=90
Just divide both sides by 2 because you want to do the opposite operation, to isolate x so if you do you get 80 so x = 80
3x - 10 = x + 4 <== ur equation
three times a number.....3x...with the x representing the number
ten less....3x - 10
is the same as...means =
that number (x) increased by 4....x + 4
so we have 3x - 10 = x + 4...
3x - 10 = x + 4
3x - x = 4 + 10
2x = 14
x = 14/2
x = 7....and that number is 7
