You solve it like this: 7x=4x-6 (subtract 4x from both sides) 3x=-6 (divide both sides by 3) x=-2
Subtract by 7x and divide by 2.
7x = 3x - 12 4x=-12 x=-3
7x + 6 - 4x = 5 + 2x + 7 subtract 6 from both sides and combine the 5 and 7 on the right: 7x - 4x = 2x + 6 subtract 2x from both sides and combine the 7x and -4x on the left: x = 6
7x = 4x - 93x = -9x = -3
You solve it like this: 7x=4x-6 (subtract 4x from both sides) 3x=-6 (divide both sides by 3) x=-2
4x - 9 = 7x + 12 Subtract 4x from both sides: -9 = 3x + 12 Subtract 12 from both sides: -21 = 3x Divide both sides by 3: x = -7
4x+9 = 7x+3 4x-7x = 3-9 -3x = -6 x = 2
Subtract by 7x and divide by 2.
3x = 7 - 4x 3x + 4x = 7 - 4x + 4x 7x = 7 7x/7 = 7/7 x = 1
-21-4x=9-7x 7x-4x=9+21 3x=30 x=30 / 3 therefore x=10
7x = 3x - 12 4x=-12 x=-3
7x + 6 - 4x = 5 + 2x + 7 subtract 6 from both sides and combine the 5 and 7 on the right: 7x - 4x = 2x + 6 subtract 2x from both sides and combine the 7x and -4x on the left: x = 6
11x + 2 = 26 + 7x Subtract 7x from both sides: 4x + 2 = 26 Subtract 2 from both sides: 4x = 24 Divide both sides by 4: x = 6
7x + y = 8 Subtract 7x from each side of the equation: y = -7x + 8
7x = 4x - 93x = -9x = -3
-3x + 2 = -7x - 22 add 7x to both sides 4x + 2 = -22 subtract 2 from both sides 4x = -24 divide by 4 x = -6 ■
