7x-2y=10 -2y=10-7x y=-5+(7/2)x y=(7/2)x-5 (Final answer)
To write the equation ( y = -7x + 6 ) in standard form, you need to rearrange it into the format ( Ax + By = C ). Start by adding ( 7x ) to both sides to get ( 7x + y = 6 ). In standard form, ( A ), ( B ), and ( C ) should be integers, so the final equation is ( 7x + y = 6 ).
7x^3. That is 7x cubed.... or 7x*7x*7x (where * means multiply). You should get 343x

(7x - 4)(7x + 4).
To simplify the expression (0.5(5-7x)8-(4x \cdot 6)), first distribute (0.5) and (8) to (5-7x) to get (4(5-7x) = 20 - 28x). Next, simplify (-4x \cdot 6) to (-24x). Combining these results, we get (20 - 28x - 24x = 20 - 52x). Thus, the final answer is (20 - 52x).
-7x + 6 + 7x - 2 = 4
To foil the equation (7x + 10)(-10x - 1), multiply each term in the first binomial by each term in the second binomial. This results in: (7x \cdot -10x = -70x^2) (7x \cdot -1 = -7x) (10 \cdot -10x = -100x) (10 \cdot -1 = -10) Now, combine the like terms: (-70x^2 - 7x - 100x - 10 = -70x^2 - 107x - 10). So, the final result is (-70x^2 - 107x - 10).
None. 7x - 1 is not equal to 7x - 7.
-7x + 5 = -9 -7x = -14 7x = 14 x = 2
3/7x + 5 = 87x(3/7x + 5) = 8(7x)3(7x/7x) + (7x)(5) = 8(7x)3 + 35x = 56x3 + 35x - 35x = 56x - 35x3 = 21x3/21 = 21x/211/7 = x
-7x-28 because you have to get the equation to it's simplest form. to do that you need to combine like term(terms that have the same variable). in this case its x. so you take -13x and add6x x to it. you get -7x. and 28 has no other like terms so you leave it alone and your final answer is -7x-28
