Question

Eu não consigo resolver essas equações me ajudem!!

2(x+3)=5-3(x-2)

7x-4=5x+6

5x+2-x+8=0

2t+7-t=3-4t

10+3x=2x+9

Answer 1

2(x+3)=5-3(x-2)

2x+6=5-3x+6

2x+3x = 5-6+6

5x = 5 ==> x = 1
===============================================
7x-4=5x+6

7x-5x= 6+4 ==> 2x = 10 ==> x = 5
==================================================
5x+2-x+8=0

4x = - 10==> x = - 10/4
=====================================================
2t+7-t=3-4t

2t-t+4t = 3-7 ==> 5t = - 4 ==> t = - 4/5
=====================================================
10+3x=2x+9

3x-2x=9-10 ==> x = - 1
