7x = 3x - 12 4x=-12 x=-3

3x+5=7x-11 5=4x-11 4x=16 x=4

13x

4x+5=7x-8 the ansewr is 3.25

4x - 7 = 5 + 7x x = -4

3x + 4x = 847x = 84divide both sides by 7x = 12

combine like terms. 3x+1+4x-5=31 3x+4x=7x 7x+1-5=31 1-5=-4 7x-4=31 then solve it 7x=35 x=5

7x = 20 + 4xSubtract 4x from each side of the equation:3x = 20Divide each side by 3 :x = 20/3

3x = 7 - 4x 3x + 4x = 7 - 4x + 4x 7x = 7 7x/7 = 7/7 x = 1

No, that's not correct.-3x + 4x = x

-21-4x=9-7x 7x-4x=9+21 3x=30 x=30 / 3 therefore x=10

-3x=-21+4x-3x-4x=-21+4x-4x-7x=-217x=217x/7=21/7x=3

7x+2 = 3x-2 7x-3x = -2-2 4x = -4 x = -1

4xy+1=3y-7x 4xy-3y=-7x-1 y(4x-3)=-7x-1 y=(-7x-1)/(4x-3)

7x + 2 = 5,6

Subtract by 7x and divide by 2.

7x + y = 4y = 4 - 7x

(2, 1)

x = -1/3

7x + 16 = 3x + 4 4x = -12 x = -3

7x = 4x - 93x = -9x = -3

Presumably this is an equation in which the value of x is to be found. 7x+8 = 4x-10 7x-4x = -10-8 3x = -18 x = -6

It is an equation and the value of x is 8

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-1-3x-4+5 = -7x-1-2x+1+6 -7x = -9x+6 2x = 6 x = 3
