8x+39 = 2x-15 6x = -54 x = -9
Set up the equation and solve: 8x + 8 = 2x +38 (subtract 2x and 8 from both sides of the equation) 6x = 30 (divide both sides of the equation by 6) x = 5
2x+6x=-9 => 8x=-9=> x=-8/9
8x+4 = 2x+28 8x-2x = 28-4 6x = 24 x = 4
10x. 'coz x=? so just add 2 & 8.
8x+39 = 2x-15 6x = -54 x = -9
8x = 2x + 15 6x = 15 x = 15/6 = 2.5
5x+8x+3x-2x = 14x
8x-7 plus 2x equals 6 plus 5x plus 2?
9+6x = 25-2x 6x+2x = 25-9 8x = 16 x = 2
Set up the equation and solve: 8x + 8 = 2x +38 (subtract 2x and 8 from both sides of the equation) 6x = 30 (divide both sides of the equation by 6) x = 5
2x+6x=-9 => 8x=-9=> x=-8/9
8x + 6 = 2x + 24 To solve, collect like terms on each side; collect the x's on the left, the numbers on the right: 8X + 6 = 2x + 24 8x - 2x = 24 - 6 6x = 18 6x / 6 = 18 / 6 x = 3
4x + 3y = 8x + y so 3y - y = 8x - 4x ie 2y = 4x so y = 2x
8x+4 = 2x+28 8x-2x = 28-4 6x = 24 x = 4
10x. 'coz x=? so just add 2 & 8.
-8x + 4y = 28 Add 8x to each side: 4y = 8x + 28 Divide both sides by 4: y = 2x + 7
