Answer:
b = 7
Step-by-step explanation:
4b + 11 = 39
Subtract 11 to both sides
4b = 39-11
4b = 28
Dividing both sides by 4
b = 7
2x + 6 = 4x - 2
Simplifying
2x + 6 = 4x + -2
Reorder the terms:
6 + 2x = 4x + -2
Reorder the terms:
6 + 2x = -2 + 4x
Solving
6 + 2x = -2 + 4x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4x' to each side of the equation.
6 + 2x + -4x = -2 + 4x + -4x
Combine like terms: 2x + -4x = -2x
6 + -2x = -2 + 4x + -4x
Combine like terms: 4x + -4x = 0
6 + -2x = -2 + 0
6 + -2x = -2
Add '-6' to each side of the equation.
6 + -6 + -2x = -2 + -6
Combine like terms: 6 + -6 = 0
0 + -2x = -2 + -6
-2x = -2 + -6
Combine like terms: -2 + -6 = -8
-2x = -8
Divide each side by '-2'.
x = 4
Simplifying
x = 4

Answer:
30
Step-by-step explanation:
in order to do this we have to look at the ratio and so in order to get from 10 to 60 on the denominator we multiply by 6 so what you do to the bottom you must also do to the top so we multiply the 5 by 6 and we get our answer of 30
