There is no visible operator between 3x and 4, for example.
It can also be written as 3x + 7. The value of the expression will depend on the value of x.
if 3x+7 = 3 then 3x = 3-7 3x = -4 then, x = -4/3
x = 7
The 7 is contant in 3x + 7, and the 3x term is variable depending on the value of x.
7
The value of x is: x=7/8. Work: 5x-3=4-3x +3 +3 ________ 5x=7-3x +3x +3x ________ 8x=7 /8 /8 ________ x=7/8
It can also be written as 3x + 7. The value of the expression will depend on the value of x.
3X - 7 = 5 add 7 to each side 3X - 7 + 7 = 5 + 7 3X = 12 divide both sides constants and coefficients by 3 X = 4 check 3(4) - 7 = 5 12 - 7 = 5 5 = 5 checks
3x + 4= 7 3x= 7-4 3x/3 = 3/3 x=1
if 3x+7 = 3 then 3x = 3-7 3x = -4 then, x = -4/3
you plug in the value of y and solve for x by algebra For example, standard form is y = mx + b Say y = 3x + 4 and you are given y = 7 then 7 = 3x + 4 3 = 3x 1 = x x = 1
It depends on the value of x. -3 = 4 -3x 3x = 7 so x =7/3 If x < 7/3 then -3 is greater if x = 7/3 then -3 is the same if x > 7/3 then -3 is smaller.
x = 7
(7x + 4) = (3x + 7) Subtract (3x + 4) from both sides of the equation. (7x + 4) - 3x - 4 = (3x + 7) - 3x - 4 4x = 3 x = 3/4 Check: (7x + 4) = 7 (3/4) + 4 = (21/4) + 4 = (21/4) + (16/4) = 37/4 (3x + 7) = 3 (3/4) + 7 = (9/4) + 7 = (9/4) + (28/4) = 37/4 Yay.
4(3x+7) = 12x + 28
The 7 is contant in 3x + 7, and the 3x term is variable depending on the value of x.
