Question

resolva as equações 3x+2=11 , 4y-3=13,5x+2x=14,30y=2/3

Answer 1

3x = 11 - 2
3x = 9
x = 9/3
x = 3

4y = 13 + 3
4y = 16
y = 16/4
y = 4

7x = 14
x = 14/7
x = 2

60y = 2
y = 2/60
y = 1/30

Answer 2

3x+2=11
3x=11-2
3x=9
x= 9/3
x= 3

4y-3=13
4y= 13+3
4y= 16
y= 16/4
y= 4

5x+2x=14
7x=14
x=14/7
x=2

30y=2/3
y=60/3
y=20
