3(30+s)=4(s+19)
*first we distribute the numbers outside the parenthesis to the numbers inside the parenthesis
3(30) + 3 (s) = 4 (s) + 4 (19)
90 + 3s = 4s + 76
*then we transpose 3s to the right side and 7g to the left side. remember that we should use the opposite sign when we transpose numbers. ( so + will be - )
90 - 76 = 4s - 3s
14 = s
*now to check, substitute s to 14
3(30 + 14) = 4(14 + 19)
3(44) = 4(33)
132 = 132 <--Yes they're equal! ^^.

3(30 + s) = 4(s + 19)
90 + 3s = 4s + 76
-3s ; -76
14 = s
substitute 14
3(30 + 14) = 4(14 + 19)
132 = 132
the equations are equal and s = 14

3(30+s)=4(s+19)
or 90 + 3s = 4s+ 76
or 90-76=4s-3s
or 14 = s

3(30+s)=4(s+19)
90+3s=4s+76
3s-4s=76-90
-s=-14
s=14
Verify: 3(30+14)=4(14+19)
3(44)=4(33)
132=132
Solution s=14 is correct

PEMDAS
parentheses
exponents
multiplication
division
addition
subtraction
in that order.
what is s equal to?
email me at jessiemarie2000@yahoo.com and i can help you i just need to know what s is
so you would do 30 + S and S + 19 first because they are in parentheses, then multiply 3 by whatever you got for 30+s and 4 by whatever you got for s+19 and i guess thas how you got the answer

distribute 3 to 30 and s and distribute 4 to s and 19
90+3s=4s+76 subtract 3s
90=s+76 subtract 76
14=s
