Answer:

some do not have numbers so I tried to make the linking as easy to understand as possible, with answers in bold.

Step-by-step explanation:

(6x + 6) + (-3 - 4x) = 2x + 3

4) = 12x - 2

(6p + 4) + (-5p + 8) = p + 12

6) = -n + 5

(-8r + 8) + (-7 - 7r) = -15r + 1

8) = 6r - 13

(1 - 6x) + (7x + 3) = x + 4

10) = -12x - 3

How do you solve 10+5(3x-4)=2x+7

Taya2010 [7]

Answer:

$x=1\dfrac{4}{13}$

Step-by-step explanation:

Given the equation

$10+5(3x-4)=2x+7$

Use distributive property:

$10+5\cdot 3x-5\cdot 4=2x+7\\ \\10+15x-20=2x+7$

Use commutative property to rewrite the equation:

$15x+10-20=2x+7$

$15x-10=2x+7$

Add 10 th both sides:

$15x-10+10=2x+7+10\\ \\15x=2x+17$

Subtract $2x:$

$15x-2x=2x+17-2x\\ \\13x=17$

Divide by 13:

$x=\dfrac{17}{13}=1\dfrac{4}{13}$
