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

3x + 2y = 8 This is an equation. It could be the equation of a line.

The value of x is: x=7/8. Work: 5x-3=4-3x +3 +3 ________ 5x=7-3x +3x +3x ________ 8x=7 /8 /8 ________ x=7/8

If you mean y = 3x+8 then the parallel equation will have the same slope and works out as y = 3x+13

3x - 4y = 8Solve for x:3x = 4y + 8x = 4/3y + 8/3Solve for y:-4y = -3x + 8y = 3/4x - 2

3x+8 = 12 Deduct 8 from both sides of the equation: 3x+8-8 = 12-8 3x = 4 Divide both sides of the equation by 3 to find the value of x: x = 4/3 or 1 and 1/3 Substituting the value of x into the original equation: 12 = 12

An equation, solution x = -10

3x + 2y = 8 This is an equation. It could be the equation of a line.

An equation, solution x = -10

It is an equation and the value of x is 7/19

3x - 4y = 10-3x - 4y = 8 -> add line 1 to line 2 3x - 4y = 100x - 8y = 18 -> -8y = 18 -> y = -18/8 = -9/4 -> 3x - 4*(-9/4) = 10 -> 3x + 9 = 10 -> 3x = 1 -> x = 1/3

3x + 8 = 20 3x = 20 - 8 3x = 12 3x = 12/3 x = 4

3x-12=12 express the equation in terms of x, 3x=12+12 then, perform the operation 3x=24 x=8 that is now the value of x.

3x-6y=-8

3x+2 = 8
