Zainab and Mahkala are 12 miles apart on a path when they start moving toward each other.
Zainab runs at a constant speed of 5 miles per hour,
and Mahkala walks at a constant speed of 3 miles per
hour. How long does it take until Mahkala and Zainab
meet?

2y= 3 2 x−2 y = − 1 3 x + 1 y=− 3 1 x+1

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?

Divide. –40 ÷ –5 a –8 b 200 c -200 d 8
