Answer:
The value of y is 48.
Step-by-step explanation:
You have to substitute the values into the equation :




Answer: 1. x= -12 2. x= 12
Step-by-step explanation:
1. 5(+3)=−45
5x+15−15=−45−15
5x= -60
5x/5 = -60/5
x = -60/5
x= -12
2. 1x/2−4=2
x/2 -4=22−4+4=2+4
/2=6
2⋅2=2⋅6
x=2⋅6
x= 12
.60 is above 50 so you round up
4.60 becomes 5.00 if you round it to the nearest tenth
