Assume that the expression is:
3x = 11 - 7x - 37
Combine like terms to get:
3x = -26 - 7x
Add both sides by 7x to get:
3x + 7x = -26 - 7x + 7x
10x = -26
Divide both sides by 10 to get:
x = -26/10
x = -13/5
x = -2 3/5
7x+6 = -3x-24 7x+3x = -24-6 10x = -30 x = -3
11
7x - 11 - 19 = 3x 4x = 30 x = 15/2
11
3x-8=7x+10x 3x-8=17x -8 = 14x -4=7x -4/7
It is an equation and the value of x is 12
7x = 3x - 12 4x=-12 x=-3
7x+6 = -3x-24 7x+3x = -24-6 10x = -30 x = -3
11
7x-3=3x+8 7x-3x=8+3 4x=11 x=11/4=2.75
7x - 11 - 19 = 3x 4x = 30 x = 15/2
(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.
7x+2 = 3x-2 7x-3x = -2-2 4x = -4 x = -1
3x = 7 - 4x 3x + 4x = 7 - 4x + 4x 7x = 7 7x/7 = 7/7 x = 1
7x - 2 = 4x + 9 3x - 2 = 9 3x = 11 x = 11/3
fist, you need to find what x is. then, multiply it by 3. then add by 5. then your answer should be 77. -or- do 77-5 the divide it by3 that's your answer FYI: that is 24
7x-11=-19+3x 4x=-19+11 4x=-8 x=-2 Check it 7x(-2)-11=-14-11=-25 And -19+(-2)x3=-19-6=-25 It works.
