Question

1. 4y-9=15 2 6x+7=-5 3 -9t+2=56

Answer 1

Answer:

1. y=6

2. x=-2

3. t=-6

Step-by-step explanation:

1.

$4y-9=15\\4y-9+9=15+9\\4y=24\\\frac{4y}{4}=\frac{24}{4}\\y=6$

2.

$6x+7=-5\\6x+7-7=-5-7\\6x=-12\\\frac{6x}{6}=\frac{-12}{6}\\x=-2$

3.

$-9t+2=56\\-9t+2-2=56-2\\-9t=54\\\frac{-9t}{-9}=\frac{54}{-9}\\t=-6$
