Question

B) 7(x+3)=4 c) 2(x+7)=27. D) 5(x-8)=25 e)3(x+4)=34 f) 4(x+5)21

Answer 1

b) 7(x+3)=4
7x+21=4
7x=4-21
7x=-17
x=-17/7
c) 2(x+7)=27
2x+14=27
2x=27-14
2x=13
x=13/2
d) 5(x-8)=25
5x-40=25
5x=25+40
5x=65
x=65/5
x=13
e) 3(x+4)=34
3x+12=34
3x=34-12
3x=22
x=22/3
f) 4(x+5)=21
4x+20=21
4x=21-20
4x=1
x=1/4
