Answer 2

To solve these equations, follow the steps below:

1. 4x - 5 = 8: Add 5 to both sides of the equation: 4x = 8 + 5 4x = 13 Divide both sides by 4 to isolate x: x = 13 / 4 x = 3.25

2. 5x - 2x + 4 = 8: Combine like terms on the left side of the equation: 3x + 4 = 8 Subtract 4 from both sides: 3x = 8 - 4 3x = 4 Divide both sides by 3 to find the value of x: x = 4 / 3 x = 1.3333 (rounded to four decimal places)

3. 7 - (3/4)x = 16: Add (3/4)x to both sides of the equation to isolate the variable term: 7 = 16 + (3/4)x Subtract 16 from both sides: -9 = (3/4)x Now, to find the value of x, multiply both sides by the reciprocal of (3/4), which is 4/3: x = -9 * (4/3) x = -36 / 3 x = -12

So, the solutions for the given equations are:

1. x = 3.25
2. x = 1.3333 (approximately)
3. x = -12
