-1/2x+2=-x+7 i need to know

ludmilkaskok [199]

$= \frac{ - 1}{ \: \: 2} x + 2 = x + 7$

$= \frac{ - 1}{ \: \: \: 2} x + 2 - x = 7$

$= \frac{ - 3}{ \: \: \: 2}x + 2 = 7$

$= \frac{ - 3}{ \: \ \: 2}x = 7 - 2$

$= \frac{ - 3}{ \: \: \: 2} x = 5$

$x = 5 \: \div \frac{ - 3}{ \: \: \: 2}$

$x = 5 \times \frac{ \: \: \: 2}{ - 3}$

$x = \frac{ - 10}{ \: \: \: 3}$

$∴ \frac{ - 1}{ \: \: \: 2} \times \frac{ - 10}{ \: \: \: 3} = \frac{ - 10}{ \: \: \: 3} + 7$

The sum of two numbers is 57. The larger number is three less than four times the smaller number. Find the numbers pls help i am

insens350 [35]

Answer: The numbers are 10.8 and 46.2.

Step-by-step explanation: The sum of two numbers is 57.

x + y = 57

Assume x is the larger number.

x - 3 = 4y

x = 4y + 3

Use subsitution.

4y + 3 + y = 57

y = -4y - 3 + 57

y = -4y + 54

5y = 54

y = 10.8

Plug in y.

x + 10.8 = 57

x = 46.2

Check.

46.2 - 3 = 4(10.8)

43.2 = 43.2
