Question

Simplify each of the following expressions:
1) -3x-(2x)
2) -3x+(-4x)
3) 4x-(-3x)
4) 2x+(-4x)

Simplify each of the following expressions:
1) 11x-(-5y)-14x-2y
2) 1/2x-1/3x

Given that x=5 and y=3, evaluate each of the following expressions:
1) 3x-2y
2)2y/3x

Answer 1

1).-3x-2x

2.)-3x-4x

3).4x+3x

4.)2x- 4x

2.1.)11x +5y-14x-2y = -3x+3y

2.2.) 1/2 x-1/3x = 3x-2x/6 =x/6

3.1.) 3×5-2×3 =15-6 =9
