Question

please solve 2(3x – 5) = 14 and 6(3x + 5) = 39 step by step

Answer 1

Answer:

Simplifying

2(3x + -5) = 14

Reorder the terms:

2(-5 + 3x) = 14

(-5 * 2 + 3x * 2) = 14

(-10 + 6x) = 14

Solving

-10 + 6x = 14

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '10' to each side of the equation.

-10 + 10 + 6x = 14 + 10

Combine like terms: -10 + 10 = 0

0 + 6x = 14 + 10

6x = 14 + 10

Combine like terms: 14 + 10 = 24

6x = 24

Divide each side by '6'.

x = 4

Simplifying

x = 4

Answer 2

4

Step-by-step explanation:

2(3x-5)=14

by the rule

2×3x=6x, 2×5=10

6x-10= 14

by the rule

6x = 10+14=24

x=24÷6

x=4

6(3x+5)=39

by the rule

6×3x=18x, 6×5=30

18x+30=39

by rule

39-30=9

x=9÷18

x=0.5
