This is a linear equation. The value x = -1 is the solution to this equation.
9x+6 = 6x+15 9x-6x = 15-6 3x = 9 x = 3
9x-53=6/x 9x2-53x=6 9x2-53x-6=0 9x2+x-54x-6=0 x(9x+1)-6(9x+1)=0 (9x+1)x(x-6)=0 9x+1=0 or x-6=0 9x=-1 or x=6 x=-1/9 or x=6
12x + 6=9x + 27 12x-9x + 6=9x - 9x + 27 subtract 9x from both sides. 3x + 6 = 27 simplify 3x + 6 - 6=27 - 6 subtract 6 from both sides. 3x=21 simplify 3x/3=21/3 divide both sides by 3 x=7 simplify 12(7) + 6=>84+6=>90 9(7) + 27=>63+27=>90 It checks out!
No.
This is a linear equation. The value x = -1 is the solution to this equation.
9x + 4 = 6 9x = 6 -4 9x = 2 x = 2/9
9x+6 = 7x+18 9x-7x = 18-6 2x = 12 x = 6
9x - 8 = 46 9x = 46 +8 9x= 54 9x/9 = 54/9 x= 6
9x + 8y = (9 x 6) + (8 x 3) = 54 + 24 = 78
9x + 7 = 15x + 1 ___-1_______-1 9x + 6 = 15x -9x_____-9x ____6=6x ____/6_/6 ____1=x x equals 1.
-9x + 4 = -50 -9x = -50 - 4 -9x = -54 -x = -6 x = 6.
7x + 9 = 51 7x = 42 x = 42/7 = 6
- 9X + 3Y = - 6 add 9X to each side 3Y = 9X - 6 divide all by 3 Y = 3X - 2
9x + 3x - 9x = 6 + 8x - 113x = 8x - 11-5x = -11x = 2.2 or 11/5
9x+6 = 6x+15 9x-6x = 15-6 3x = 9 x = 3
9x+3y = 6 3y = -9x+6 y = -3x+2 which is now in slope-intercept form
