3p+2(p+4)=-12
3p+2p+8=-12
5p=-12-8
5p=-20
p=-20/5
p=-4 answer.
Proof:
3*-4+2(-4+4)=-12
-12+0=-12
-12=-12
-------------------------------------------
4x+rt=x+16
4x-x=16-rt
3x=16-rt
x=(16-rt)/3 answer.
Proof:
4(16-rt)/3+rt=(16-rt)/3+16
(64-4rt)/3+rt=(16-rt)/3+16
(64-4rt+3rt)/3=(16-rt+16*3)/3
(64-rt)/3=(16-rt+48)/3
(64-rt)/3=(64-rt)/3
---------------------------------------------
2(pq+4)=3x-pq
2pq+8=3x-pq
3x=2pq+pq+8
3x=3pq+8
x=pq+8/3 answer.
Proof:
2(pq+4)=3(pq+8/3)-pq
2pq+8=3pq+24/3-pq
2pq+8=2pq+8
----------------------------------------
1+3(5x-2)=5(x+1)
1+15x-6=5x+5
15x-5x=5+6-1
10x=10
x=10/10
x=1 answer.
proof:
1+3(5*1-2)=5(1+1)
1+3(5-2)=5*2
1+3*3=10
1+9=10
10=10
