Well, let's take a moment to appreciate the beauty of this expression. When we combine like terms, 2x and 7x, we add their coefficients together to get 9x. It's like blending different colors on your palette to create a harmonious masterpiece. Just remember, math is like painting - with a little practice and patience, you can create something wonderful.
7x = 18 - 2x 7x + 2x = 18 9x = 18 x = 2
(7x)(2x - 27) This means multiply the '7x' to each term in the other set of brackets. Hence 14x^2 - 189x
2x = 7x - 10 subtract the 7x from both sides 2x - 7x = -10 -5x = -10 divide both sides by -5 x = 2
2x+7x-10=4x+3-2x 9x-10=2x+3 7x=13 x=13/7ans
7x - 9x = -2x
If it's + 7x, the answer is (2x + 3)(5x - 4) If it's - 7x, the answer is (2x - 3)(5x + 4)
2x-6 < 5+7x 2x-7x < 5+6 -5x < 11 x > -2.5
If you mean 2x+4(7x-1) then 2x+28x-4=30x-4=2(15x-2) If you mean 2x+4(7x)-1 then 2x+28x-1=30x-1
(7x-9=-2x)+4x=2x
2x+4+7x-4 is the same as 9x
2x+18=7x-30 7x-30=2x=18 7x-2x=18+30 5x=48 x=9.6
7 plus 7x--2x plus 3 is: 7 + 7x + 2x + 3 = 0 9x + 10 = 0 9x = -10 x = -10/9 = -1 1/9
