4(7+V)
4 times a number added to 7 times the number equals 33
-1 Here is why: let x be the number, 4x+7=3 4x=3-7=-4 so 4x=-1 and x is -1
the answer to the question above is that 4 times 7 is 28 and 14 times 2 = 28
It can be: 7-4x as an algebraic expression
It could be: (4*11.25)+7 = 52
When -25=4x+7 Then -25-7 = 4x And -32 = 4x So the number is -32/4 = -8
x/4+7=-31
( 1 + 7x )
7x - 8 = 3x + 4 4x - 8 = 4 4x = 12 x = 3 Check it. 21 - 8 = 9 + 4 It checks.
18 is a solution to the equation 4 plus 7 times a number where the result is 9 times that number.
-3x + 7 < -3 -3x < 4 x > -(4/3) ■
4(7+V)
4 times a number added to 7 times the number equals 33
2x + 7 = 15 Subtract 7 from both sides: 2x = 8 Divide both sides by 2: x = 4
It is: 4 times (7+1) = 32
4x - 7
