4x + 10 + 3x = 40 - 3x 4x + 10 + 3x + 3x = 40 20x = 40 x = 2
To find the gradient of the equation 2y = 4x + 1, we first need to rewrite it in slope-intercept form, y = mx + b, where m is the gradient. Dividing by 2 on both sides gives y = 2x + 0.5. Therefore, the gradient is 2.
x - 2
6x - 4y
It is possible.
3x - 12 = 10x - 15 - 6x -10 3x - 12 = 4x -25 3x + 13 = 4x 13 = 4x - 3x 13 = x None?
x= -11
4x - 7 = 5 + 7x x = -4
minus 4 plus 9 = 5, so 5x
It is: minus 1.25

x= Negative 4
6x plus 3y minus 2x plus 5y equals 4x plus 8y.
The equation 4x + 5 = 2 has the solution 4x = -3 and x = - 3/4 (minus 3/4).
2x+7x-10=4x+3-2x 9x-10=2x+3 7x=13 x=13/7ans
