The missing measure is 70.

-8x-27=-7\left(1+2x\right)+2x

Answer:

$x=5$

Step-by-step explanation:

$-8x-27=-7\left(1+2x\right)+2x$

Expand:

$-8x-27=-7\times 1-7\times 2x+2x$

$-8x-27=-7-12x$

Add 27 to both sides:

$-8x-27+27=-7-12x+27$

$-8x=-12x+20$

Add 12x to both sides:

$-8x+12x=-12x+20+12x$

$4x=20$

Divide both sides by 4:

$\frac{4x}{4}=\frac{20}{4}$

$x=5$

Answer: The answer would be x < 10/7

Step-by-step explanation:

Rearrange:

Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :

7*x (10)>0

Step by step solution :

STEP

Pulling out like terms

1.1 Pull out like factors :

7x - 10 = -1 • (7x + 10)

Equation at the end of step

STEP 2

2.1 Multiply both sides by (-1)

Flip the inequality sign since you are multiplying by a negative number

7x+10 < 0

2.2 Divide both sides by 7

x+(10/7) < 0

Solve Basic Inequality :

2.3 Subtract 10/7 from both sides

x < 10/7

Inequality Plot :

2.4 Inequality plot for
