Answer:

−0.516667

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

12x+2.2=−4

Step 2:  Subtract 2.2 from both sides.

12x+2.2−2.2=−4−2.2

12x=−6.2

Step 3: Divide both sides by 12.

12x

12

=

−6.2

12

x=−0.516667

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}
