22=7x+1 (take 1 of each side of the equals) 21=7x (divide each side by seven) 3=x (BAM! answer)
7x + 1 = 20 7x = 19 x = 19/7 x = 2.714285 recurring (that is, 2.714285714285..)
(1, -1)
7x + 6x - 1 = 0 7x + 6x = 1 13x = 1 x = (1/13) This is not calculus btw. Its basic algebra.
4xy+1=3y-7x 4xy-3y=-7x-1 y(4x-3)=-7x-1 y=(-7x-1)/(4x-3)
11x11=121

11 * 11 equals 121.
its pretty easy: 3-2 = 1 so if u multiply 1 x 7x, it equals 7x

7x + 29 = 36 7x + 29 - 29 = 36 - 29 7x = 7 7x/7 = 7/7 x = 1
yes.
4xy+1=3y-7x 4xy-3y=-7x-1 y(4x-3)=-7x-1 y=(-7x-1)/(4x-3)
8x-1 = 7x+2 Add 1 to both sides: 8x = 7x+3 Subtract 7x from both sides: 1x = 3 ie x = 3
