3. X= 11
4. M= 12
5. B= 5
6. Y= 3

Work:
1). 5(x + 2) = 510
5(100 + 2)= 510
5(102)=510
X=100

Please mark brainliest

Answer 2

5(x+2)=510
5x+10=510
510-10=500
5x/5=500/5
x=100

4(2c+5)=28
8c+20=28
8c/8=8/8
c=1

3(x-5)=30
3x-15=30
3x=45
3x/3=45/3
x=15

n(3+4)=84
n3+n4=84
n7/7=84/7
n=12

5(b-3)=10
5b-15=10
5b=25
5b/5=25/5
b=5

1.5(2y+5)=__?
y=__?
