Question

1. 2-2/3x=4
2. 3/4(x+3)+1/2(x-1=0)
3. 2x-3/3+4x+4/=2x+3
tolong ya

Answer 1

1. → -2/3x = 4-2
-2/3x = 2
x = 2÷ -2/3
x= 2 × -3/2
x = -3
2. → 3/4x + 9/4 + ½x - ½ =0
→ 3/4x + 2/4x + 9/4 - 2/4 = 0
→ 5/4x +7/4 = 0
→ 5/4x = -7/4
→ 5x = -7 → x = -7/5
3. → 2x-3/3 = 2x+3 - 4x - 4
→ 2x-3/3 = -2x-1
2x-3 = 3(-2x-1)
2x-3 = -6x-3
2x+6x = -3 + 3
8x = 0 → x = 0
semoga dapat membantu
