=  \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

Does the point (6,3) satisfy the equation y = 4(x – 5)?
Darina [25.2K]

Answer:

No

Step-by-step explanation:

plug (6,3) into the given equation to find out

3 = 4(6-5)

3 = 4(1)

3 = 4
