Answer:

1. x= 11.2

2. x= 8

Step-by-step explanation:

$124+5x=180\\-124 -124\\5x=56\\\frac{5x}{5} = \frac{56}{5} \\ x=11.2$

Check:

$124+5(11.2)=180\\124+56=180\\180=180$

$7x-6=50\\+6 +6\\7x=56\\\frac{7x}{7} = \frac{56}{7} \\x=8$

Check:

$7(8)-6=50\\56-6=50\\50=50$

Ratling [72]

Answer:

Equation: x + (x+ 1) = 67

Step-by-step explanation:

We want to find two consecutive integers.

Let them be labeled as x and x + 1

We want x + (x + 1) = 67

x is the smaller number

x + 1 is the largest

We can solve for x.

x + (x + 1) = 2x + 1 = 67

2x = 66

x = 33

The largest integer is 34
