Question

1. 7r-7=2r+18
2. 8x-3=15x+18
3. 6y-6=4y+16
4. 3(x-4)=5(x+2)

Need a little help on these

Answer 1

I'm honestly stuck on this question so I'm not so sure but I can try and give it a go??

Answer 2

Number 1
7r−7=2r+18
Subtract 2r from both sides.
7r−7−2r=18
Combine 7r and −2r to get 5r.
5r−7=18
Add 7 to both sides.
5r=18+7
Add 18 and 7 to get 25.
5r=25
Divide both sides by 5.
r= 25/5
Divide 25 by 5 to get 5.
r=5

Number 2
8x−3=15x+18
Subtract 15x from both sides.
8x−3−15x=18
Combine 8x and −15x to get −7x.
−7x−3=18
Add 3 to both sides.
−7x=18+3
Add 18 and 3 to get 21.
−7x=21
Divide both sides by −7.
x= 21/-7
Divide 21 by −7 to get −3.
x=−3

Number 3
6y−6=4y+16
Subtract 4y from both sides.
6y−6−4y=16
Combine 6y and −4y to get 2y.
2y−6=16
Add 6 to both sides.
2y=16+6
Add 16 and 6 to get 22.
2y=22
Divide both sides by 2.
y= 22/2
Divide 22 by 2 to get 11.
y=11

Number 4
3(x−4)=5(x+2)
Use the distributive property to multiply 3 by x−4.
3x−12=5(x+2)
Use the distributive property to multiply 5 by x+2.
3x−12=5x+10
Subtract 5x from both sides.
3x−12−5x=10
Combine 3x and −5x to get −2x.
−2x−12=10
Add 12 to both sides.
−2x=10+12
Add 10 and 12 to get 22.
−2x=22
Divide both sides by −2.
x= 22/-2
Divide 22 by −2 to get −11.
x=−11

Hope this helps!!
