x+1+7x-3 Simplify adding the x terms and the numbers separately So it becomes x+7x+1-3 = 8x-2
3
Step 1. 7 = 7x +2 Step 2. subtract 2 from both sides: 7 - 2 = 7x + 2 - 2 and simplify: 5 = 7x Step 3. divide both sides by 7: (5/7) = (7x/7) and simplify 5/7 = x x = 5/7 or about 0.714285
i got 42 divided 7x
15xy-2xy-7x+x=13xy-6x
you begin with -7x+y=-20 and 9x-3y=36 7x-7x+y=-20+7x (add 7x to both sides) y=7x-20 (simplify) 9x-9x-3y=36-9x (subtract 9x from both sides) -3y/-3=36/-3-9x/-3 (divide both sides by -3) y=3x-12 (simplify) y=y so 7x-20=3x-12 7x+20-20=3x-12+20 (add 20 to both sides) 7x=3x+8 (simplify) 7x-3x=3x-3x+8 (add 3x to both sides) 4x=8 (simplify) 4x/4=8/4 (divide by 4 on both sides) x=2 (simplify) 9(2)-3y=36 (plug in 2 for x) 18-3y=36 (simplify) 18-18-3y=36-18 (subtract 18 from both sides) -3y=18 (simplify) -3y/-3=18/-3 (divide by -3 on both sides) y=-6 (simplify) the point is 2,-6 (x,y)

7x 2= 14
It is: 12x
i got 42 divided 7x
18 + 7x - 12 + 5x = ?18 - 12+ 7x - 5x = ?6 + 2x = ?
7x + 7 + 6x - 9 = 13x - 2
15xy-2xy-7x+x=13xy-6x
4x-5.
If you mean: 5x+9+7x-11 then it simplifies to 12x-2
