To solve the equation (2x + 12(1 - 3x) = 7), first distribute the 12: (2x + 12 - 36x = 7). Combine like terms: (-34x + 12 = 7). Subtract 12 from both sides: (-34x = -5). Finally, divide by -34 to find (x = \frac{5}{34}).
7/2x = 3 Multiply both sides by 2x: 7 = 3*2x = 6x Divide both sides by 6 = 7/6 = x ie x = 1.1666...
if 2x + y = 7, what is the value of y when x = 3?
It is an equation and the value of x is 1
7(2 + 2x) is 78 when x = 3. = 5,764,801.
It is: 2x squared +5x -7 = 0 and the value of x = -7/2 or 1
(The original question was misphrased.) 4x-7 = 2x+5 resolves as 2x-7 = 5 2x = 12 x = 6
7/2x = 3 Multiply both sides by 2x: 7 = 3*2x = 6x Divide both sides by 6 = 7/6 = x ie x = 1.1666...

X=-7
x+7 = 2x 2x = x+7 2x-x = 7 x = 7
x = 7

2x+3=9 2x=9-3 2x=6 2x/2=6/2 X=3
The mathematical inequality that represents the relationship described is 14 < 2x. This inequality states that the value of 14 is less than twice the value of x. To solve for x, we can divide both sides of the inequality by 2 to isolate x, giving us x > 7. Therefore, any value of x greater than 7 will satisfy the given condition.
