13 less than 4 times a number 13 less than is "-13" 4 times a number is "4x" 4x-13■
The answer to this question '4 less than x' is x-4.
It's easiest to break this into parts. First look at the numbers being multiplied (4 times a number). Since you don't know this number, you have to use x. So 4 times x is 4x. Then you need to know what 3 less than 4x is, so you would simply subtract, giving you 4x-3.
8x + 8 = 4x 4x + 8 = 0 4x = -8 x = -2
VV2-4x+4y-4=0
13 less than 4 times a number 13 less than is "-13" 4 times a number is "4x" 4x-13■
(2x - 4)/(4x + 5) - 12
The answer to this question '4 less than x' is x-4.
4x-3
The expression is: 4x-500
4x - 500
-4x=7y-28 -4x+28=7y -4x/7+4=y A line with a y-int of 4 and a slope of -4/7
4x - 11 = 49 4x = 60 x = 15
x=(-500)+(4x) BY:105
4x + 2 < 8x - 2Add 2 to each side:4x + 4 < 8xSubtract 4x from each side:4 < 4xDivide each side by 4:1 < x
-9 < 4x + 3 < 11 Subtract 3 from each expression: -12 < 4x < 8 Divide each term by 4: -3 < x < 2
4x-6=22, 4x=28, 4/4(x)=28/4, x=7. That is how you get the answer to be 7
