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
